The memop test currently does not have any output (unless one of the
TEST_ASSERT statement fails), so it's hard to say for a user whether
a certain new sub-test has been included in the binary or not. Let's
make this a little bit more user-friendly and include some TAP output
via the kselftests.h interface.
