rbutil: Update and fix unit tests.

- Fix changed dependencies and provide real stubs.
- Update to use QTest global data for test table, so individual test
  vector entries show up as individual tests. That way a single
  comparison failing doesn't make all appear as failed and provide
  better indication what went wrong.
