    gst: Don't rebuild the video sink for the plugin
    
    The plugin can just depend on libcogl-gst instead of relinking in the
    code from it. If we don't do this then if an application directly
    links against libcogl-gst then GStreamer will additionally pull in the
    plugin library and it will have two copies of the symbols. This is
    quite likely to get in a mess.
