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.
