    services: mpd: Do not eagerly look for a user.
    
    Running 'guix system search mpd' would throw a backtrace because the
    mpd-shepherd-service service start Gexp contained an unquoted call to
    'getpwnam', which would look for a missing 'mpd' user and fail.
    
    * gnu/services/audio.scm (mpd-shepherd-service): gexp-unquote only the
    relevant variable rather than the whole expression.
