If access to /dev/dri/renderD128 fails, then qemu with 3d graphics will
fail to start and errors are rather cryptic like:
qemu-system-x86_64: egl: render node init failed
To fix this, users likely need to
* modprobe vgem
* add their user to "render" group to write to /dev/dri/renderD128
If access is not available due to missing HW, driver or failing access,
then skip the test:
