Reintroduce the test_NULL_unmapped() selftest

c/s f571b0b "Implement the hvm32 environment" introduced a guard to the
test_NULL_unmapped() selftest, as it is inapplicable in an unpaged
environment.

However, CONFIG_PAGING wasn't ever defined (it disappeared during
development), causing the selftest to be unconditionally omitted even in paged
environments.

Reintroduce the check, based on CONFIG_PAGING_LEVELS being non-zero.
