tests/prime_vgem: Skip basic-read/write subtests if not supported
As we've agreed that using I915_GEM_PREAD/PWRITE IOCTLs on dma-buf
objects doesn't make much sense, we are not going to extend their
handlers in the i915 driver with new processing paths required for them
to work correctly with dma-buf objects on future hardware with no
mappable aperture. When running on that kind of hardware, just skip
subtests which use those IOCTLs.
v2: Examine pread/pwrite ABI, not mmap ABI (Chris)
v3: Don't use "no mappable GGTT" wording in commit message (Chris)
