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.

- * This program can either change modification time of the given
- * file(s) or just print it. The program does not change atime or
- * ctime (their values are explicitly preserved).
- *
- * The mtime can be changed to an absolute value:
- *
- *	test-tool chmtime =<seconds> file...
- *
- * Relative to the current time as returned by time(3):
- *
- *	test-tool chmtime =+<seconds> (or =-<seconds>) file...
- *
- * Or relative to the current mtime of the file:
- *
- *	test-tool chmtime <seconds> file...
- *	test-tool chmtime +<seconds> (or -<seconds>) file...
- *
- * Examples:
- *
- * To print the mtime and the file name use --verbose and set
- * the file mtime offset to 0:
- *
- *	test-tool chmtime -v +0 file
- *
- * To print only the mtime use --get:
- *
- *	test-tool chmtime --get file
- *
- * To set the mtime to current time:
- *
- *	test-tool chmtime =+0 file
- *
- * To set the file mtime offset to +1 and print the new value:
- *
- *	test-tool chmtime --get +1 file
- *
