thunderbolt: Allow KUnit tests to be built also when CONFIG_USB4=m
This adds a bit more build coverage for the tests even though these are not expected to be enabled by normal users and distros. In order to make this working we need to open-code kunit_test_suite() and call the relevant functions directly in the driver init/exit hook.
