We couldn't remove the old code without making changes to igt to work
out what the appropriate GT directory would be for the test. That is
still unknowable from userspace... So as a matter of convenience we kept
the old entry point so that we could dump everything under the device.

More work could be done to remove the duplication of debug code, but
equally we could use more specialised debug info for the igts.
