[PATCH 2/2] drm/tests: Change "igt_" prefix to "drm_"

["Maíra Canal" <mairacanal@riseup.net>]

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_" prefix, making the tests' names independent from the tool
used.
