[Beignet] [PATCH] Utests: Allow testing cl_intel_accelerator via ICD

[Rebecca N. Palmer]

> [**** Chuanbo ****] This utest test intel extension cl_intel_accelerator and cl_intel_motion_estimation, so it's not beignet specific,
> but it's intel specific. You can add code such as:
> 	if (!cl_check_accelerator() && !cl_check_motion_estimation()) 
> The implementation of cl_check_accelerator and cl_check_motion_estimation are similar as cl_check_subgroups.

I was going for "not finding this on a beignet device means extension
lookup is broken (which would be a bug), not finding it on other
devices is normal"; this version keeps that while allowing the test
to run on non-beignet devices that do have it, but I haven't has time
to test it (or to check whether we already have a test for extension
lookup).
