selftests/mm: move zeropage test into uffd unit tests
Simplifies it a bit along the way, e.g., drop the never used offset field
(which was always the 1st page so offset=0).
Introduce uffd_register_with_ioctls() out of uffd_register() to detect
uffdio_register.ioctls got returned. Check that automatically when testing
UFFDIO_ZEROPAGE on different types of memory (and kernel).
