Subject: Makefile: Quiet errors from git describe

With new git versions, it is an error to invoke git inside a repository
owned by someone else.  This manifested as

    $ sudo make install
    fatal: unsafe repository ('/home/tavianator/code/bfs' is owned by someone else)
    To add an exception for this directory, call:

            git config --global --add safe.directory /home/tavianator/code/bfs

Work around it with `2>/dev/null`.  This should also help if git is not
installed, but .git/ still exists.
