tests/acceptance: Re-enable the microblaze test

The microblaze kernel sometimes gets stuck during boot (ca. 1 out of 200
times), so we disabled the corresponding acceptance tests some months
ago. However, it's likely better to check that the kernel is still
starting than to not testing it at all anymore. Move the test to
a separate file, enable it again and check for an earlier console
message that should always appear.
