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.

-test_description='Break and then rename
-
-We have two very different files, file0 and file1, registered in a tree.
-
-We update file1 so drastically that it is more similar to file0, and
-then remove file0.  With -B, changes to file1 should be broken into
-separate delete and create, resulting in removal of file0, removal of
-original file1 and creation of completely rewritten file1.  The latter
-two are then merged back into a single "complete rewrite".
-
-Further, with -B and -M together, these three modifications should
-turn into rename-edit of file0 into file1.
-
-Starting from the same two files in the tree, we swap file0 and file1.
-With -B, this should be detected as two complete rewrites.
-
-Further, with -B and -M together, these should turn into two renames.
