backend-drm/drm-virtual: Hang off the drm_backend

Browse Source 
This is needed by drm_output_fini_egl() to be able to retrieve the
backend out of the drm_output on the shutdown path of the compositor.

Both the remoting plug-in and the pipewire plug-in are users of the
drm-virtual API and as such they would trigger a crash when shutting
down the compositor, as we're not setting up any backend whatsoever.
