Always perform copy/delete on OSError

Extends the fix in #400 to handle all potential OSError errno values and
attempt a copy/delete in all cases. For example, a combination
cross-device move and a permissions change would throw errno 1 instead
of errno 18, which wasn't caught here. Instead of messing with
individual errno numbers, just always attempt a copy/delete and let
those throw their own exceptions if they don't work either.
