tools/testing/selftests: fix guard region test tmpfs assumption
The current implementation of the guard region tests assume that /tmp is
mounted as tmpfs, that is shmem.
This isn't always the case, and at least one instance of a spurious test
failure has been reported as a result.
This assumption is unsafe, rushed and silly - and easily remedied by
simply using memfd, so do so.
We also have to fixup the readonly_file test to explicitly only be
applicable to file-backed cases.
