kunit: Taint the kernel when KUnit tests are run
Make KUnit trigger the new TAINT_TEST taint when any KUnit test is run.
Due to KUnit tests not being intended to run on production systems, and
potentially causing problems (or security issues like leaking kernel
addresses), the kernel's state should not be considered safe for
production use after KUnit tests are run.
This both marks KUnit modules as test modules using MODULE_INFO() and
manually taints the kernel when tests are run (which catches builtin
tests).
