drm/i915/selftests: allow misaligned_pin test work with unmappable memory

In case of Small BAR configurations stolen local memory can be unmappable.
Since the test does not touch the memory, passing I915_BO_ALLOC_GPU_ONLY
flag to i915_gem_object_create_region, will prevent -ENOSPC error from
_i915_gem_object_stolen_init.
