emacs: Remove the no longer maintained vc-git package.

vc-git is distributed with Emacs since version 22.2, and is maintained
in the Emacs CVS tree. This file is obsolete and causes trouble for
people who want to add contrib/emacs to their load-path.

-;;; Commentary:
-
-;; This file contains a VC backend for the git version control
-;; system.
-;;
-;; To install: put this file on the load-path and add GIT to the list
-;; of supported backends in `vc-handled-backends'; the following line,
-;; placed in your ~/.emacs, will accomplish this:
-;;
-;;     (add-to-list 'vc-handled-backends 'GIT)
-;;
-;; TODO
-;;  - changelog generation
-;;  - working with revisions other than HEAD
