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.

- * Note: we only report the filename of the process executable; the
- *       only way to get its full pathname is to use OpenProcess()
- *       and GetModuleFileNameEx() or QueryfullProcessImageName()
- *       and that seems rather expensive (on top of the cost of
- *       getting the snapshot).
- *
- * Note: we compute the set of parent processes by walking the PPID
- *       link in each visited PROCESSENTRY32 record.  This search
- *       stops when an ancestor process is not found in the snapshot
- *       (because it exited before the current or intermediate parent
- *       process exited).
- *
- *       This search may compute an incorrect result if the PPID link
- *       refers to the PID of an exited parent and that PID has been
- *       recycled and given to a new unrelated process.
- *
- *       Worse, it is possible for a child or descendant of the
- *       current process to be given the recycled PID and cause a
- *       PPID-cycle.  This would cause an infinite loop building our
- *       parent process array.
- *
- * Note: for completeness, the "System Idle" process has PID=0 and
- *       PPID=0 and could cause another PPID-cycle.  We don't expect
- *       Git to be a descendant of the idle process, but because of
- *       PID recycling, it might be possible to get a PPID link value
- *       of 0.  This too would cause an infinite loop.
- *
- * Therefore, we keep an array of the visited PPIDs to guard against
- * cycles.
- *
- * We use a fixed-size array rather than ALLOC_GROW to keep things
- * simple and avoid the alloc/realloc overhead.  It is OK if we
- * truncate the search and return a partial answer.
