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.

- * Some cases use stdio, but want to flush after the write

- * behaviour - not buffering excessively).
- *
- * Of course, if the flush happened within the write itself,
- * we've already lost the error code, and cannot report it any
- * more. So we just ignore that case instead (and hope we get
- * the right error code on the flush).

- * If the file handle is stdout, and stdout is a file, then skip the
- * flush entirely since it's not needed.
