    backend: Make sure dvdreadsrc never gets used
    
    resindvd isn't ported to GStreamer 1.0 yet, and dvdreadsrc is
    not something we want users to think is the DVD playback experience
    of Totem.
    
    Remove dvdreadsrc from the plugin registry so it's never auto-plugged
    when looking for a dvd:// handler.
