[Beignet] utests difficulty on Halo GT4

[Andrew Lavin]

Hi,

I just received a Skull Canyon NUC with Intel Graphics Skylake Halo GT4. I
built beignet master but the unit tests fail. I am running Ubuntu 16.04
with the default 4.4.0-22-generic kernel. It is my first try with beignet,
apologies if I am doing something wrong.
