From: Marc-André Lureau <marcandre.lureau@redhat.com>
This will check virtio/vhost-user-vga & virgl are correctly initialized
by the Linux kernel on an egl-headless display.
There are many other things that could be checked, but that's a start. I
also don't know yet how to nicely skip on incompatible host &
configurations.
