    git: Add ssh authentication support.
    If Guile-Git revision is >= 0.3.0, use SSH agent authentication method for
    both clone and fetch calls.
    * guix/git.scm (auth-supported?): New variable,
    (clone*): set auth-method to ssh-agent if the variable above is true,
    (update-cached-checkout): ditto.
