minigbm: i915: use DRM_IOCTL_I915_GEM_MMAP when needed
The following three CTS tests fail with an i915 backend:
EncodeVirtualDisplayWithCompositionTest#testRendering800x480Locally
EncodeVirtualDisplayWithCompositionTest#testRenderingMaxResolutionRemotely
EncodeVirtualDisplayWithCompositionTest#testVirtualDisplayRecycles
The reason for the failures is the bo_map() function calls
DRM_IOCTL_I915_GEM_MMAP_GTT with untiled buffers, leading to
Surface::dequeueBuffer not completing in time.
Note the final form of unmap will be a clfush.
BUG=none
TEST=The 3 CTS tests pass.
