intel: tell libdrm whether we want a cpu-ready or gpu-ready BO for regions.
This lets us avoid allocing new buffers for renderbuffers, finalized miptrees, and PBO-uploaded textures when there's an unreferenced but still active one cached, while also avoiding CPU waits for batchbuffers and CPU-uploaded textures. The size of BOs allocated for a desktop running current GL cairogears on i915 is cut in half with this. Note that this means we require libdrm 2.4.5.
