Making kunit itself buildable as a module allows for "always-on" kunit configuration; specifying CONFIG_KUNIT=m means the module is built but only used when loaded. Kunit test modules will load kunit.ko as an implicit dependency, so simply running "modprobe my-kunit-tests" will load the tests along with the kunit module and run them.
