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='Three way merge with read-tree -m
-
-This test tries three-way merge with read-tree -m
-
-There is one ancestor (called O for Original) and two branches A
-and B derived from it.  We want to do a 3-way merge between A and
-B, using O as the common ancestor.
-
-    merge A O B
-
-Decisions are made by comparing contents of O, A and B pathname
-by pathname.  The result is determined by the following guiding
-principle:
-
- - If only A does something to it and B does not touch it, take
-   whatever A does.
-
- - If only B does something to it and A does not touch it, take
-   whatever B does.
-
- - If both A and B does something but in the same way, take
-   whatever they do.
-
- - If A and B does something but different things, we need a
-   3-way merge:
-
-   - We cannot do anything about the following cases:
-
-     * O does not have it.  A and B both must be adding to the
-       same path independently.
-
-     * A deletes it.  B must be modifying.
-
-   - Otherwise, A and B are modifying.  Run 3-way merge.
-
-First, the case matrix.
-
- - Vertical axis is for A'\''s actions.
- - Horizontal axis is for B'\''s actions.
