With the introduction of KUnit, IGT is no longer the only option to run the DRM unit tests, as the tests can be run through kunit-tool or on real hardware with CONFIG_KUNIT. Therefore, remove the "igt_" prefix from the tests and replace it with the "drm_test_" prefix, making the tests' names independent from the tool used.
