Commit 961bcdf9 ("drm/tests: Change "igt_" prefix to "drm_test_"")
introduced a new naming convention for the KUnit tests present in the
DRM subsystem: "drm_test_<module>_<test name>".

This naming convention is very convenient because it allows to easily
run all subsystem tests or all driver tests using kunit.py's wildcards.

Follow the naming conventions used in the DRM subsystem adapted to the
HID subsystem: "hid_test_<module>_<test name>".
