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.

-How to write RIGHT test cases
-=============================
-
-Insert the word "ChangeMe" (exactly this form) at a distance of
-at least two lines from the line that must appear in the hunk header.
-
-The text that must appear in the hunk header must contain the word
-"right", but in all upper-case, like in the title above.
-
-To mark a test case that highlights a malfunction, insert the word
-BROKEN in all lower-case somewhere in the file.
-
-This text is a bit twisted and out of order, but it is itself a
-test case for the default hunk header pattern. Know what you are doing
-if you change it.
-
-BTW, this tests that the head line goes to the hunk header, not the line
-of equal signs.
