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.

-gc.aggressiveDepth::
-	The depth parameter used in the delta compression
-	algorithm used by 'git gc --aggressive'.  This defaults
-	to 50, which is the default for the `--depth` option when
-	`--aggressive` isn't in use.
-+
-See the documentation for the `--depth` option in
-linkgit:git-repack[1] for more details.
-
-gc.aggressiveWindow::
-	The window size parameter used in the delta compression
-	algorithm used by 'git gc --aggressive'.  This defaults
-	to 250, which is a much more aggressive window size than
-	the default `--window` of 10.
-+
-See the documentation for the `--window` option in
-linkgit:git-repack[1] for more details.
-
-gc.auto::
-	When there are approximately more than this many loose
-	objects in the repository, `git gc --auto` will pack them.
-	Some Porcelain commands use this command to perform a
-	light-weight garbage collection from time to time.  The
-	default value is 6700.
-+
-Setting this to 0 disables not only automatic packing based on the
-number of loose objects, but any other heuristic `git gc --auto` will
-otherwise use to determine if there's work to do, such as
-`gc.autoPackLimit`.
-
-gc.autoPackLimit::
-	When there are more than this many packs that are not
-	marked with `*.keep` file in the repository, `git gc
-	--auto` consolidates them into one larger pack.  The
-	default value is 50.  Setting this to 0 disables it.
-	Setting `gc.auto` to 0 will also disable this.
-+
-See the `gc.bigPackThreshold` configuration variable below. When in
-use, it'll affect how the auto pack limit works.
-
-gc.autoDetach::
-	Make `git gc --auto` return immediately and run in background
-	if the system supports it. Default is true.
-
-gc.bigPackThreshold::
-	If non-zero, all packs larger than this limit are kept when
-	`git gc` is run. This is very similar to `--keep-base-pack`
-	except that all packs that meet the threshold are kept, not
-	just the base pack. Defaults to zero. Common unit suffixes of
-	'k', 'm', or 'g' are supported.
-+
-Note that if the number of kept packs is more than gc.autoPackLimit,
-this configuration variable is ignored, all packs except the base pack
-will be repacked. After this the number of packs should go below
-gc.autoPackLimit and gc.bigPackThreshold should be respected again.
-+
-If the amount of memory estimated for `git repack` to run smoothly is
-not available and `gc.bigPackThreshold` is not set, the largest pack
-will also be excluded (this is the equivalent of running `git gc` with
-`--keep-base-pack`).
-
-gc.writeCommitGraph::
-	If true, then gc will rewrite the commit-graph file when
-	linkgit:git-gc[1] is run. When using `git gc --auto`
-	the commit-graph will be updated if housekeeping is
-	required. Default is true. See linkgit:git-commit-graph[1]
-	for details.
-
-gc.logExpiry::
-	If the file gc.log exists, then `git gc --auto` will print
-	its content and exit with status zero instead of running
-	unless that file is more than 'gc.logExpiry' old.  Default is
-	"1.day".  See `gc.pruneExpire` for more ways to specify its
-	value.
-
-gc.packRefs::
-	Running `git pack-refs` in a repository renders it
-	unclonable by Git versions prior to 1.5.1.2 over dumb
-	transports such as HTTP.  This variable determines whether
-	'git gc' runs `git pack-refs`. This can be set to `notbare`
-	to enable it within all non-bare repos or it can be set to a
-	boolean value.  The default is `true`.
-
-gc.pruneExpire::
-	When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
-	Override the grace period with this config variable.  The value
-	"now" may be used to disable this grace period and always prune
-	unreachable objects immediately, or "never" may be used to
-	suppress pruning.  This feature helps prevent corruption when
-	'git gc' runs concurrently with another process writing to the
-	repository; see the "NOTES" section of linkgit:git-gc[1].
-
-gc.worktreePruneExpire::
-	When 'git gc' is run, it calls
-	'git worktree prune --expire 3.months.ago'.
-	This config variable can be used to set a different grace
-	period. The value "now" may be used to disable the grace
-	period and prune `$GIT_DIR/worktrees` immediately, or "never"
-	may be used to suppress pruning.
-
-gc.reflogExpire::
-gc.<pattern>.reflogExpire::
-	'git reflog expire' removes reflog entries older than
-	this time; defaults to 90 days. The value "now" expires all
-	entries immediately, and "never" suppresses expiration
-	altogether. With "<pattern>" (e.g.
-	"refs/stash") in the middle the setting applies only to
-	the refs that match the <pattern>.
-
-gc.reflogExpireUnreachable::
-gc.<pattern>.reflogExpireUnreachable::
-	'git reflog expire' removes reflog entries older than
-	this time and are not reachable from the current tip;
-	defaults to 30 days. The value "now" expires all entries
-	immediately, and "never" suppresses expiration altogether.
-	With "<pattern>" (e.g. "refs/stash")
-	in the middle, the setting applies only to the refs that
-	match the <pattern>.
-+
-These types of entries are generally created as a result of using `git
-commit --amend` or `git rebase` and are the commits prior to the amend
-or rebase occurring.  Since these changes are not part of the current
-project most users will want to expire them sooner, which is why the
-default is more aggressive than `gc.reflogExpire`.
-
-gc.rerereResolved::
-	Records of conflicted merge you resolved earlier are
-	kept for this many days when 'git rerere gc' is run.
-	You can also use more human-readable "1.month.ago", etc.
-	The default is 60 days.  See linkgit:git-rerere[1].
-
-gc.rerereUnresolved::
-	Records of conflicted merge you have not resolved are
-	kept for this many days when 'git rerere gc' is run.
-	You can also use more human-readable "1.month.ago", etc.
-	The default is 15 days.  See linkgit:git-rerere[1].
