backend/drm: return secondary backend DRM FD
It can be useful for compositors to get the real DRM FD instead of
the one from the parent compositor. For instance, some compositors
might want to perform some DRM IOCTLs there to check the driver
name, fetch some DRM resources, etc. This will also be a requirement
for direct scanout on secondary GPUs.
