Becuase late_initcall() is used, if these modules are built-in, this
would preclude the ability to test things prior to this part of the
kernel under UML or whatever architecture runs the tests. So, this
limits the scope of testing. Small detail but the scope whould be
documented.

What is this TAP thing? Why should we care what version it is on?
Why are we printing this?

If we make the last test case NULL, we'd just check for test_case here,
and save ourselves an extra few bytes per test module. Any reason why
the last test case cannot be NULL?

I believe if we used struct kunit_module *kmodule it would be much
clearer who's init this is.
