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.

-SYNOPSIS
---------
-$GIT_DIR/*
-
-DESCRIPTION
------------
-
-A Git repository comes in two different flavours:
-
- * a `.git` directory at the root of the working tree;
-
- * a `<project>.git` directory that is a 'bare' repository
-   (i.e. without its own working tree), that is typically used for
-   exchanging histories with others by pushing into it and fetching
-   from it.
-
-*Note*: Also you can have a plain text file `.git` at the root of
-your working tree, containing `gitdir: <path>` to point at the real
-directory that has the repository.  This mechanism is often used for
-a working tree of a submodule checkout, to allow you in the
-containing superproject to `git checkout` a branch that does not
-have the submodule.  The `checkout` has to remove the entire
-submodule working tree, without losing the submodule repository.
-
-These things may exist in a Git repository.
-
-objects::
-	Object store associated with this repository.  Usually
-	an object store is self sufficient (i.e. all the objects
-	that are referred to by an object found in it are also
-	found in it), but there are a few ways to violate it.
-+
-. You could have an incomplete but locally usable repository
-by creating a shallow clone.  See linkgit:git-clone[1].
-. You could be using the `objects/info/alternates` or
-`$GIT_ALTERNATE_OBJECT_DIRECTORIES` mechanisms to 'borrow'
-objects from other object stores.  A repository with this kind
-of incomplete object store is not suitable to be published for
-use with dumb transports but otherwise is OK as long as
-`objects/info/alternates` points at the object stores it
-borrows from.
-+
-This directory is ignored if $GIT_COMMON_DIR is set and
-"$GIT_COMMON_DIR/objects" will be used instead.
-
-objects/[0-9a-f][0-9a-f]::
-	A newly created object is stored in its own file.
-	The objects are splayed over 256 subdirectories using
-	the first two characters of the sha1 object name to
-	keep the number of directory entries in `objects`
-	itself to a manageable number. Objects found
-	here are often called 'unpacked' (or 'loose') objects.
-
-objects/pack::
-	Packs (files that store many objects in compressed form,
-	along with index files to allow them to be randomly
-	accessed) are found in this directory.
-
-objects/info::
-	Additional information about the object store is
-	recorded in this directory.
-
-objects/info/packs::
-	This file is to help dumb transports discover what packs
-	are available in this object store.  Whenever a pack is
-	added or removed, `git update-server-info` should be run
-	to keep this file up to date if the repository is
-	published for dumb transports.  'git repack' does this
-	by default.
-
-objects/info/alternates::
-	This file records paths to alternate object stores that
-	this object store borrows objects from, one pathname per
-	line. Note that not only native Git tools use it locally,
-	but the HTTP fetcher also tries to use it remotely; this
-	will usually work if you have relative paths (relative
-	to the object database, not to the repository!) in your
-	alternates file, but it will not work if you use absolute
-	paths unless the absolute path in filesystem and web URL
-	is the same. See also `objects/info/http-alternates`.
-
-objects/info/http-alternates::
-	This file records URLs to alternate object stores that
-	this object store borrows objects from, to be used when
-	the repository is fetched over HTTP.
-
-refs::
-	References are stored in subdirectories of this
-	directory.  The 'git prune' command knows to preserve
-	objects reachable from refs found in this directory and
-	its subdirectories.
-	This directory is ignored (except refs/bisect,
-	refs/rewritten and refs/worktree) if $GIT_COMMON_DIR is
-	set and "$GIT_COMMON_DIR/refs" will be used instead.
-
-refs/heads/`name`::
-	records tip-of-the-tree commit objects of branch `name`
-
-refs/tags/`name`::
-	records any object name (not necessarily a commit
-	object, or a tag object that points at a commit object).
-
-refs/remotes/`name`::
-	records tip-of-the-tree commit objects of branches copied
-	from a remote repository.
-
-refs/replace/`<obj-sha1>`::
-	records the SHA-1 of the object that replaces `<obj-sha1>`.
-	This is similar to info/grafts and is internally used and
-	maintained by linkgit:git-replace[1]. Such refs can be exchanged
-	between repositories while grafts are not.
-
-packed-refs::
-	records the same information as refs/heads/, refs/tags/,
-	and friends record in a more efficient way.  See
-	linkgit:git-pack-refs[1]. This file is ignored if $GIT_COMMON_DIR
-	is set and "$GIT_COMMON_DIR/packed-refs" will be used instead.
-
-HEAD::
-	A symref (see glossary) to the `refs/heads/` namespace
-	describing the currently active branch.  It does not mean
-	much if the repository is not associated with any working tree
-	(i.e. a 'bare' repository), but a valid Git repository
-	*must* have the HEAD file; some porcelains may use it to
-	guess the designated "default" branch of the repository
-	(usually 'master').  It is legal if the named branch
-	'name' does not (yet) exist.  In some legacy setups, it is
-	a symbolic link instead of a symref that points at the current
-	branch.
-+
-HEAD can also record a specific commit directly, instead of
-being a symref to point at the current branch.  Such a state
-is often called 'detached HEAD.'  See linkgit:git-checkout[1]
-for details.
-
-config::
-	Repository specific configuration file. This file is ignored
-	if $GIT_COMMON_DIR is set and "$GIT_COMMON_DIR/config" will be
-	used instead.
-
-config.worktree::
-	Working directory specific configuration file for the main
-	working directory in multiple working directory setup (see
-	linkgit:git-worktree[1]).
-
-branches::
-	A slightly deprecated way to store shorthands to be used
-	to specify a URL to 'git fetch', 'git pull' and 'git push'.
-	A file can be stored as `branches/<name>` and then
-	'name' can be given to these commands in place of
-	'repository' argument.  See the REMOTES section in
-	linkgit:git-fetch[1] for details.  This mechanism is legacy
-	and not likely to be found in modern repositories. This
-	directory is ignored if $GIT_COMMON_DIR is set and
-	"$GIT_COMMON_DIR/branches" will be used instead.
-
-
-hooks::
-	Hooks are customization scripts used by various Git
-	commands.  A handful of sample hooks are installed when
-	'git init' is run, but all of them are disabled by
-	default.  To enable, the `.sample` suffix has to be
-	removed from the filename by renaming.
-	Read linkgit:githooks[5] for more details about
-	each hook. This directory is ignored if $GIT_COMMON_DIR is set
-	and "$GIT_COMMON_DIR/hooks" will be used instead.
-
-common::
-	When multiple working trees are used, most of files in
-	$GIT_DIR are per-worktree with a few known exceptions. All
-	files under 'common' however will be shared between all
-	working trees.
-
-index::
-	The current index file for the repository.  It is
-	usually not found in a bare repository.
-
-sharedindex.<SHA-1>::
-	The shared index part, to be referenced by $GIT_DIR/index and
-	other temporary index files. Only valid in split index mode.
-
-info::
-	Additional information about the repository is recorded
-	in this directory. This directory is ignored if $GIT_COMMON_DIR
-	is set and "$GIT_COMMON_DIR/info" will be used instead.
-
-info/refs::
-	This file helps dumb transports discover what refs are
-	available in this repository.  If the repository is
-	published for dumb transports, this file should be
-	regenerated by 'git update-server-info' every time a tag
-	or branch is created or modified.  This is normally done
-	from the `hooks/update` hook, which is run by the
-	'git-receive-pack' command when you 'git push' into the
-	repository.
-
-info/grafts::
-	This file records fake commit ancestry information, to
-	pretend the set of parents a commit has is different
-	from how the commit was actually created.  One record
-	per line describes a commit and its fake parents by
-	listing their 40-byte hexadecimal object names separated
-	by a space and terminated by a newline.
-+
-Note that the grafts mechanism is outdated and can lead to problems
-transferring objects between repositories; see linkgit:git-replace[1]
-for a more flexible and robust system to do the same thing.
-
-info/exclude::
-	This file, by convention among Porcelains, stores the
-	exclude pattern list. `.gitignore` is the per-directory
-	ignore file.  'git status', 'git add', 'git rm' and
-	'git clean' look at it but the core Git commands do not look
-	at it.  See also: linkgit:gitignore[5].
-
-info/attributes::
-	Defines which attributes to assign to a path, similar to per-directory
-	`.gitattributes` files.   See also: linkgit:gitattributes[5].
-
-info/sparse-checkout::
-	This file stores sparse checkout patterns.
-	See also: linkgit:git-read-tree[1].
-
-remotes::
-	Stores shorthands for URL and default refnames for use
-	when interacting with remote repositories via 'git fetch',
-	'git pull' and 'git push' commands.  See the REMOTES section
-	in linkgit:git-fetch[1] for details.  This mechanism is legacy
-	and not likely to be found in modern repositories. This
-	directory is ignored if $GIT_COMMON_DIR is set and
-	"$GIT_COMMON_DIR/remotes" will be used instead.
-
-logs::
-	Records of changes made to refs are stored in this directory.
-	See linkgit:git-update-ref[1] for more information. This
-	directory is ignored (except logs/HEAD) if $GIT_COMMON_DIR is
-	set and "$GIT_COMMON_DIR/logs" will be used instead.
-
-logs/refs/heads/`name`::
-	Records all changes made to the branch tip named `name`.
-
-logs/refs/tags/`name`::
-	Records all changes made to the tag named `name`.
-
-shallow::
-	This is similar to `info/grafts` but is internally used
-	and maintained by shallow clone mechanism.  See `--depth`
-	option to linkgit:git-clone[1] and linkgit:git-fetch[1]. This
-	file is ignored if $GIT_COMMON_DIR is set and
-	"$GIT_COMMON_DIR/shallow" will be used instead.
-
-commondir::
-	If this file exists, $GIT_COMMON_DIR (see linkgit:git[1]) will
-	be set to the path specified in this file if it is not
-	explicitly set. If the specified path is relative, it is
-	relative to $GIT_DIR. The repository with commondir is
-	incomplete without the repository pointed by "commondir".
-
-modules::
-	Contains the git-repositories of the submodules.
-
-worktrees::
-	Contains administrative data for linked
-	working trees. Each subdirectory contains the working tree-related
-	part of a linked working tree. This directory is ignored if
-	$GIT_COMMON_DIR is set, in which case
-	"$GIT_COMMON_DIR/worktrees" will be used instead.
-
-worktrees/<id>/gitdir::
-	A text file containing the absolute path back to the .git file
-	that points to here. This is used to check if the linked
-	repository has been manually removed and there is no need to
-	keep this directory any more. The mtime of this file should be
-	updated every time the linked repository is accessed.
-
-worktrees/<id>/locked::
-	If this file exists, the linked working tree may be on a
-	portable device and not available. The presence of this file
-	prevents `worktrees/<id>` from being pruned either automatically
-	or manually by `git worktree prune`. The file may contain a string
-	explaining why the repository is locked.
-
-worktrees/<id>/config.worktree::
-	Working directory specific configuration file.
