Replace the old kconfig check tests with new ones, that do not rely on:
* any kernel config in pmaports
* the currently required kconfig options set in pmb/config/__init__.py
This will make it much easier to change the required options, and moves
the testsuite a bit more towards making it completely independent from
current pmaports state.
