Create a basic subtests which allows to properly cleanup after
any failure or a skip. Also while at this, move an igt header
to proper place.

This is redundant with the next line?

Similar redundancy here? If drm_fd = -1, the test will be skipped in the
first fixture itself and this check is not needed?
With these removed the patch LGTM,

You are right, I will remove this and one at first fixture above.
