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.

-#
-# Performance test for the fsmonitor feature which enables git to talk to a
-# file system change monitor and avoid having to scan the working directory
-# for new or modified files.
-#
-# By default, the performance test will utilize the Watchman file system
-# monitor if it is installed.  If Watchman is not installed, it will use a
-# dummy integration script that does not report any new or modified files.
-# The dummy script has very little overhead which provides optimistic results.
-#
-# The performance test will also use the untracked cache feature if it is
-# available as fsmonitor uses it to speed up scanning for untracked files.
-#
-# There are 3 environment variables that can be used to alter the default
-# behavior of the performance test:
-#
-# GIT_PERF_7519_UNTRACKED_CACHE: used to configure core.untrackedCache
-# GIT_PERF_7519_SPLIT_INDEX: used to configure core.splitIndex
-# GIT_PERF_7519_FSMONITOR: used to configure core.fsMonitor
-#
-# The big win for using fsmonitor is the elimination of the need to scan the
-# working directory looking for changed and untracked files. If the file
-# information is all cached in RAM, the benefits are reduced.
-#
-# GIT_PERF_7519_DROP_CACHE: if set, the OS caches are dropped between tests
