QA: Add TITLE_BLOCK tests

Add some unit tests on TITLE_BLOCK

This commit also requires some mocks so the libcommon stuff
can work:

* Needs a Kiface() function to be linkable
* Needs some stuff from common to be build specially
* Needs to define itself as one of the unit-having programs
  to appease the units defines.
