selftests/mm: run the MAP_DROPPABLE selftest
The test was not being run by the selftest framework so it was never
noticed that it would fail with an assertion failure on configs without
support for MAP_DROPPABLE. Update the test so that it is skipped instead
when MAP_DROPPABLE is not supported, and add it to the mmap category so
that the test is run by the framework.
