rust/faux: Drop #[repr(transparent)] from faux::Registration

I think this change got missed during review, we don't need
 #[repr(transparent)] since Registration just holds a single NonNull. This
attribute had originally been added by me when I was still figuring out how
the bindings should look like but got committed by mistake. So, just drop
it.
