As far as upstream's concerned, I'm okay with both because libvirt has to add
another version specific capability enum for this anyway. It's been broken
since libvirt 4.6.0 where I added egl-headless graphics type. Luckily, even
though it's far from optimal, a working solution exists, just change the
permissions on the device.
