drm/i915/selftests: Allow huge_gem_object to kick the shrinker 



A new fi-cml-dallium CI machine has 8G and apparently plenty free, yet
fails some selftests with ENOMEM. The failures all seem to be from
huge_gem_object which does not try very hard to allocate memory,
skipping reclaim entirely. Let's try a bit harder and direct reclaim
before failing.
