chore(3p/git): Unvendor git and track patches instead r/2903

This was vendored a long time ago under the expectation that keeping
it in sync with cgit would be easier this way, but it has proven not
to be a big issue.

On the other hand, a vendored copy of git is an annoying maintenance
burden. It is much easier to rebase the single (dottime) patch that we
have.

This removes the vendored copy of git and instead passes the git
source code to cgit via `pkgs.srcOnly`, which includes the applied
patch so that cgit can continue rendering dottime.

-DESCRIPTION
------------
-
-Clones a repository into a newly created directory, creates
-remote-tracking branches for each branch in the cloned repository
-(visible using `git branch --remotes`), and creates and checks out an
-initial branch that is forked from the cloned repository's
-currently active branch.
-
-After the clone, a plain `git fetch` without arguments will update
-all the remote-tracking branches, and a `git pull` without
-arguments will in addition merge the remote master branch into the
-current master branch, if any (this is untrue when "--single-branch"
-is given; see below).
-
-This default configuration is achieved by creating references to
-the remote branch heads under `refs/remotes/origin` and
-by initializing `remote.origin.url` and `remote.origin.fetch`
-configuration variables.
-
-
-OPTIONS
--------
--l::
---local::
-	When the repository to clone from is on a local machine,
-	this flag bypasses the normal "Git aware" transport
-	mechanism and clones the repository by making a copy of
-	HEAD and everything under objects and refs directories.
-	The files under `.git/objects/` directory are hardlinked
-	to save space when possible.
-+
-If the repository is specified as a local path (e.g., `/path/to/repo`),
-this is the default, and --local is essentially a no-op.  If the
-repository is specified as a URL, then this flag is ignored (and we
-never use the local optimizations).  Specifying `--no-local` will
-override the default when `/path/to/repo` is given, using the regular
-Git transport instead.
-
---no-hardlinks::
-	Force the cloning process from a repository on a local
-	filesystem to copy the files under the `.git/objects`
-	directory instead of using hardlinks. This may be desirable
-	if you are trying to make a back-up of your repository.
-
--s::
---shared::
-	When the repository to clone is on the local machine,
-	instead of using hard links, automatically setup
-	`.git/objects/info/alternates` to share the objects
-	with the source repository.  The resulting repository
-	starts out without any object of its own.
-+
-*NOTE*: this is a possibly dangerous operation; do *not* use
-it unless you understand what it does. If you clone your
-repository using this option and then delete branches (or use any
-other Git command that makes any existing commit unreferenced) in the
-source repository, some objects may become unreferenced (or dangling).
-These objects may be removed by normal Git operations (such as `git commit`)
-which automatically call `git maintenance run --auto`. (See
-linkgit:git-maintenance[1].) If these objects are removed and were referenced
-by the cloned repository, then the cloned repository will become corrupt.
-+
-Note that running `git repack` without the `--local` option in a repository
-cloned with `--shared` will copy objects from the source repository into a pack
-in the cloned repository, removing the disk space savings of `clone --shared`.
-It is safe, however, to run `git gc`, which uses the `--local` option by
-default.
-+
-If you want to break the dependency of a repository cloned with `--shared` on
-its source repository, you can simply run `git repack -a` to copy all
-objects from the source repository into a pack in the cloned repository.
-
---reference[-if-able] <repository>::
-	If the reference repository is on the local machine,
-	automatically setup `.git/objects/info/alternates` to
-	obtain objects from the reference repository.  Using
-	an already existing repository as an alternate will
-	require fewer objects to be copied from the repository
-	being cloned, reducing network and local storage costs.
-	When using the `--reference-if-able`, a non existing
-	directory is skipped with a warning instead of aborting
-	the clone.
-+
-*NOTE*: see the NOTE for the `--shared` option, and also the
-`--dissociate` option.
-
---dissociate::
-	Borrow the objects from reference repositories specified
-	with the `--reference` options only to reduce network
-	transfer, and stop borrowing from them after a clone is made
-	by making necessary local copies of borrowed objects.  This
-	option can also be used when cloning locally from a
-	repository that already borrows objects from another
-	repository--the new repository will borrow objects from the
-	same repository, and this option can be used to stop the
-	borrowing.
-
--q::
---quiet::
-	Operate quietly.  Progress is not reported to the standard
-	error stream.
-
--v::
---verbose::
-	Run verbosely. Does not affect the reporting of progress status
-	to the standard error stream.
-
---progress::
-	Progress status is reported on the standard error stream
-	by default when it is attached to a terminal, unless `--quiet`
-	is specified. This flag forces progress status even if the
-	standard error stream is not directed to a terminal.
-
---server-option=<option>::
-	Transmit the given string to the server when communicating using
-	protocol version 2.  The given string must not contain a NUL or LF
-	character.  The server's handling of server options, including
-	unknown ones, is server-specific.
-	When multiple `--server-option=<option>` are given, they are all
-	sent to the other side in the order listed on the command line.
-
--n::
---no-checkout::
-	No checkout of HEAD is performed after the clone is complete.
-
---bare::
-	Make a 'bare' Git repository.  That is, instead of
-	creating `<directory>` and placing the administrative
-	files in `<directory>/.git`, make the `<directory>`
-	itself the `$GIT_DIR`. This obviously implies the `--no-checkout`
-	because there is nowhere to check out the working tree.
-	Also the branch heads at the remote are copied directly
-	to corresponding local branch heads, without mapping
-	them to `refs/remotes/origin/`.  When this option is
-	used, neither remote-tracking branches nor the related
-	configuration variables are created.
-
---sparse::
-	Initialize the sparse-checkout file so the working
-	directory starts with only the files in the root
-	of the repository. The sparse-checkout file can be
-	modified to grow the working directory as needed.
-
---filter=<filter-spec>::
-	Use the partial clone feature and request that the server sends
-	a subset of reachable objects according to a given object filter.
-	When using `--filter`, the supplied `<filter-spec>` is used for
-	the partial clone filter. For example, `--filter=blob:none` will
-	filter out all blobs (file contents) until needed by Git. Also,
-	`--filter=blob:limit=<size>` will filter out all blobs of size
-	at least `<size>`. For more details on filter specifications, see
-	the `--filter` option in linkgit:git-rev-list[1].
-
---mirror::
-	Set up a mirror of the source repository.  This implies `--bare`.
-	Compared to `--bare`, `--mirror` not only maps local branches of the
-	source to local branches of the target, it maps all refs (including
-	remote-tracking branches, notes etc.) and sets up a refspec configuration such
-	that all these refs are overwritten by a `git remote update` in the
-	target repository.
-
--o <name>::
---origin <name>::
-	Instead of using the remote name `origin` to keep track
-	of the upstream repository, use `<name>`.
-
--b <name>::
---branch <name>::
-	Instead of pointing the newly created HEAD to the branch pointed
-	to by the cloned repository's HEAD, point to `<name>` branch
-	instead. In a non-bare repository, this is the branch that will
-	be checked out.
-	`--branch` can also take tags and detaches the HEAD at that commit
-	in the resulting repository.
-
--u <upload-pack>::
---upload-pack <upload-pack>::
-	When given, and the repository to clone from is accessed
-	via ssh, this specifies a non-default path for the command
-	run on the other end.
-
---template=<template_directory>::
-	Specify the directory from which templates will be used;
-	(See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
-
--c <key>=<value>::
---config <key>=<value>::
-	Set a configuration variable in the newly-created repository;
-	this takes effect immediately after the repository is
-	initialized, but before the remote history is fetched or any
-	files checked out.  The key is in the same format as expected by
-	linkgit:git-config[1] (e.g., `core.eol=true`). If multiple
-	values are given for the same key, each value will be written to
-	the config file. This makes it safe, for example, to add
-	additional fetch refspecs to the origin remote.
-+
-Due to limitations of the current implementation, some configuration
-variables do not take effect until after the initial fetch and checkout.
-Configuration variables known to not take effect are:
-`remote.<name>.mirror` and `remote.<name>.tagOpt`.  Use the
-corresponding `--mirror` and `--no-tags` options instead.
-
---depth <depth>::
-	Create a 'shallow' clone with a history truncated to the
-	specified number of commits. Implies `--single-branch` unless
-	`--no-single-branch` is given to fetch the histories near the
-	tips of all branches. If you want to clone submodules shallowly,
-	also pass `--shallow-submodules`.
-
---shallow-since=<date>::
-	Create a shallow clone with a history after the specified time.
-
---shallow-exclude=<revision>::
-	Create a shallow clone with a history, excluding commits
-	reachable from a specified remote branch or tag.  This option
-	can be specified multiple times.
-
---[no-]single-branch::
-	Clone only the history leading to the tip of a single branch,
-	either specified by the `--branch` option or the primary
-	branch remote's `HEAD` points at.
-	Further fetches into the resulting repository will only update the
-	remote-tracking branch for the branch this option was used for the
-	initial cloning.  If the HEAD at the remote did not point at any
-	branch when `--single-branch` clone was made, no remote-tracking
-	branch is created.
-
---no-tags::
-	Don't clone any tags, and set
-	`remote.<remote>.tagOpt=--no-tags` in the config, ensuring
-	that future `git pull` and `git fetch` operations won't follow
-	any tags. Subsequent explicit tag fetches will still work,
-	(see linkgit:git-fetch[1]).
-+
-Can be used in conjunction with `--single-branch` to clone and
-maintain a branch with no references other than a single cloned
-branch. This is useful e.g. to maintain minimal clones of the default
-branch of some repository for search indexing.
-
---recurse-submodules[=<pathspec>]::
-	After the clone is created, initialize and clone submodules
-	within based on the provided pathspec.  If no pathspec is
-	provided, all submodules are initialized and cloned.
-	This option can be given multiple times for pathspecs consisting
-	of multiple entries.  The resulting clone has `submodule.active` set to
-	the provided pathspec, or "." (meaning all submodules) if no
-	pathspec is provided.
-+
-Submodules are initialized and cloned using their default settings. This is
-equivalent to running
-`git submodule update --init --recursive <pathspec>` immediately after
-the clone is finished. This option is ignored if the cloned repository does
-not have a worktree/checkout (i.e. if any of `--no-checkout`/`-n`, `--bare`,
-or `--mirror` is given)
-
---[no-]shallow-submodules::
-	All submodules which are cloned will be shallow with a depth of 1.
-
---[no-]remote-submodules::
-	All submodules which are cloned will use the status of the submodule's
-	remote-tracking branch to update the submodule, rather than the
-	superproject's recorded SHA-1. Equivalent to passing `--remote` to
-	`git submodule update`.
-
---separate-git-dir=<git dir>::
-	Instead of placing the cloned repository where it is supposed
-	to be, place the cloned repository at the specified directory,
-	then make a filesystem-agnostic Git symbolic link to there.
-	The result is Git repository can be separated from working
-	tree.
-
--j <n>::
---jobs <n>::
-	The number of submodules fetched at the same time.
-	Defaults to the `submodule.fetchJobs` option.
-
-<repository>::
-	The (possibly remote) repository to clone from.  See the
-	<<URLS,GIT URLS>> section below for more information on specifying
-	repositories.
-
-<directory>::
-	The name of a new directory to clone into.  The "humanish"
-	part of the source repository is used if no directory is
-	explicitly given (`repo` for `/path/to/repo.git` and `foo`
-	for `host.xz:foo/.git`).  Cloning into an existing directory
-	is only allowed if the directory is empty.
