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.

-branch.autoSetupMerge::
-	Tells 'git branch', 'git switch' and 'git checkout' to set up new branches
-	so that linkgit:git-pull[1] will appropriately merge from the
-	starting point branch. Note that even if this option is not set,
-	this behavior can be chosen per-branch using the `--track`
-	and `--no-track` options. The valid settings are: `false` -- no
-	automatic setup is done; `true` -- automatic setup is done when the
-	starting point is a remote-tracking branch; `always` --
-	automatic setup is done when the starting point is either a
-	local branch or remote-tracking
-	branch. This option defaults to true.
-
-branch.autoSetupRebase::
-	When a new branch is created with 'git branch', 'git switch' or 'git checkout'
-	that tracks another branch, this variable tells Git to set
-	up pull to rebase instead of merge (see "branch.<name>.rebase").
-	When `never`, rebase is never automatically set to true.
-	When `local`, rebase is set to true for tracked branches of
-	other local branches.
-	When `remote`, rebase is set to true for tracked branches of
-	remote-tracking branches.
-	When `always`, rebase will be set to true for all tracking
-	branches.
-	See "branch.autoSetupMerge" for details on how to set up a
-	branch to track another branch.
-	This option defaults to never.
-
-branch.sort::
-	This variable controls the sort ordering of branches when displayed by
-	linkgit:git-branch[1]. Without the "--sort=<value>" option provided, the
-	value of this variable will be used as the default.
-	See linkgit:git-for-each-ref[1] field names for valid values.
-
-branch.<name>.remote::
-	When on branch <name>, it tells 'git fetch' and 'git push'
-	which remote to fetch from/push to.  The remote to push to
-	may be overridden with `remote.pushDefault` (for all branches).
-	The remote to push to, for the current branch, may be further
-	overridden by `branch.<name>.pushRemote`.  If no remote is
-	configured, or if you are not on any branch, it defaults to
-	`origin` for fetching and `remote.pushDefault` for pushing.
-	Additionally, `.` (a period) is the current local repository
-	(a dot-repository), see `branch.<name>.merge`'s final note below.
-
-branch.<name>.pushRemote::
-	When on branch <name>, it overrides `branch.<name>.remote` for
-	pushing.  It also overrides `remote.pushDefault` for pushing
-	from branch <name>.  When you pull from one place (e.g. your
-	upstream) and push to another place (e.g. your own publishing
-	repository), you would want to set `remote.pushDefault` to
-	specify the remote to push to for all branches, and use this
-	option to override it for a specific branch.
-
-branch.<name>.merge::
-	Defines, together with branch.<name>.remote, the upstream branch
-	for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
-	branch to merge and can also affect 'git push' (see push.default).
-	When in branch <name>, it tells 'git fetch' the default
-	refspec to be marked for merging in FETCH_HEAD. The value is
-	handled like the remote part of a refspec, and must match a
-	ref which is fetched from the remote given by
-	"branch.<name>.remote".
-	The merge information is used by 'git pull' (which at first calls
-	'git fetch') to lookup the default branch for merging. Without
-	this option, 'git pull' defaults to merge the first refspec fetched.
-	Specify multiple values to get an octopus merge.
-	If you wish to setup 'git pull' so that it merges into <name> from
-	another branch in the local repository, you can point
-	branch.<name>.merge to the desired branch, and use the relative path
-	setting `.` (a period) for branch.<name>.remote.
-
-branch.<name>.mergeOptions::
-	Sets default options for merging into branch <name>. The syntax and
-	supported options are the same as those of linkgit:git-merge[1], but
-	option values containing whitespace characters are currently not
-	supported.
-
-branch.<name>.rebase::
-	When true, rebase the branch <name> on top of the fetched branch,
-	instead of merging the default branch from the default remote when
-	"git pull" is run. See "pull.rebase" for doing this in a non
-	branch-specific manner.

-When `merges` (or just 'm'), pass the `--rebase-merges` option to 'git rebase'
-so that the local merge commits are included in the rebase (see
-linkgit:git-rebase[1] for details).
-+
-When `preserve` (or just 'p', deprecated in favor of `merges`), also pass
-`--preserve-merges` along to 'git rebase' so that locally committed merge
-commits will not be flattened by running 'git pull'.
-+
-When the value is `interactive` (or just 'i'), the rebase is run in interactive
-mode.
-+
-*NOTE*: this is a possibly dangerous operation; do *not* use
-it unless you understand the implications (see linkgit:git-rebase[1]
-for details).
-
-branch.<name>.description::
-	Branch description, can be edited with
-	`git branch --edit-description`. Branch description is
-	automatically added in the format-patch cover letter or
-	request-pull summary.
