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.

-USAGE: git mw preview [--remote|-r <remote name>] [--autoload|-a]
-                      [--output|-o <output filename>] [--verbose|-v]
-                      <blob> | <filename>
-
-DESCRIPTION:
-Preview is an utiliy to preview local content of a mediawiki repo as if it was
-pushed on the remote.
-
-For that, preview searches for the remote name of the current branch's
-upstream if --remote is not set. If that remote is not found or if it
-is not a mediawiki, it lists all mediawiki remotes configured and asks
-you to replay your command with the --remote option set properly.
-
-Then, it searches for a file named 'filename'. If it's not found in
-the current dir, it will assume it's a blob.
-
-The content retrieved in the file (or in the blob) will then be parsed
-by the remote mediawiki and combined with a template retrieved from
-the mediawiki.
-
-Finally, preview will save the HTML result in a file. and autoload it
-in your default web browser if the option --autoload is present.
-
-OPTIONS:
-    -r <remote name>, --remote <remote name>
-        If the remote is a mediawiki, the template and the parse engine
-        used for the preview will be those of that remote.
-        If not, a list of valid remotes will be shown.
-
-    -a, --autoload
-        Try to load the HTML output in a new tab (or new window) of your
-        default web browser.
-
-    -o <output filename>, --output <output filename>
-        Change the HTML output filename. Default filename is based on the
-        input filename with its extension replaced by '.html'.
-
-    -v, --verbose
-        Show more information on what's going on under the hood.
