Passing a cleanup callback from newlib testcase is always a mistake
because it's never executed. I would prefer keeping the check in the
library.

It does not matter in case of tmpdir_cleanup() since that function only
prints a warning message. What about removing the tmpdir_cleanup()
cleanup instead? It does not seem to be useful to me anyway.
