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.

-#!/bin/sh
-#
-# This test covers the handling of objects which might have old
-# mtimes in the filesystem (because they were used previously)
-# and are just now becoming referenced again.
-#
-# We're going to do two things that are a little bit "fake" to
-# help make our simulation easier:
-#
-#   1. We'll turn off reflogs. You can still run into
-#      problems with reflogs on, but your objects
-#      don't get pruned until both the reflog expiration
-#      has passed on their references, _and_ they are out
-#      of prune's expiration period. Dropping reflogs
-#      means we only have to deal with one variable in our tests,
-#      but the results generalize.
-#
-#   2. We'll use a temporary index file to create our
-#      works-in-progress. Most workflows would mention
-#      referenced objects in the index, which prune takes
-#      into account. However, many operations don't. For
-#      example, a partial commit with "git commit foo"
-#      will use a temporary index. Or they may not need
-#      an index at all (e.g., creating a new commit
-#      to refer to an existing tree).
