Do not try to load hybrid driver on unsupported platforms #532

Currently, the intel driver tries to load hybrid_drv_video.so in each case. On IVB and older machines, it doesn't make sense to have it installed as they're not supported. When it's not installed, intel driver complains:

$ vainfo

While having it installed doesn't hurt, I would prefer not to waste even 5MB of storage space (for cmrt and libva-intel-hybrid-driver) just to shut up a useless warning message.
