Note that the default_config is NULL, but will be updated by a
subsequent patch to use the extern one.

Note that here I'm not creating a file with the default_config.

I think it's a bad idea; the conf file wouldn't be human readable, and
in case gst-omx is updated with a new default_config it will not be
used because the old one is already stored.
