clients/simple-dmabuf-feedback: fix bound global versions

Browse Source 
It's invalid for a client to pass the compositor's supported version
directly to wl_registry_bind. For instance, under wlroots the client
will bind to wl_output version 4 and crash because it doesn't handle
the new "name" event.
