lib: igt_fork_hang_helper must be run in fixtures

Because it opens an intel-specific drm fd. Fixes crashes when running
igt on no-intel.

* This is useful to exercise slow running code (such as aperture placement)
* which needs to be robust against a GPU reset.
*
* In tests with subtests this function can be called outside of failure
* catching code blocks like #igt_fixture or #igt_subtest.
* This function automatically skips when test requirements aren't met using
* igt_skip().
