tests/acceptance: Add a test with the Fedora 31 kernel and initrd 

This initrd contains a virtio-net and a virtio-gpu kernel module,
so we can check that we can set a MAC address for the network device
and whether we can hot-plug and -unplug a virtio-crypto device.
But the most interesting part is maybe that we can also successfully
write some stuff into the emulated framebuffer of the virtio-gpu
device and make sure that we can read back that data from a screenshot.
