lib: Use HAS_GPU_RESET rather than opencode our guess
Uses kernel commit 49e4d842f0d0892c3d26c93a81b9f22c1467030e
Author: Chris Wilson <chris@chris-wilson.co.uk>

drm/i915: Report to userspace if we have a (presumed) working GPU reset
to determine whether the kernel has a working GPU reset before injecting
a hang (and so skip tests requring hang recovery if not available).
