[PATCH 11/12] automation: stubdom test with boot from CDROM



Based on the initial stubdomain test add booting from CDOM. It's
significantly different in terms of emulated devices (contrary to PV
disk, the cdrom is backed by qemu), so test that path too.
Schedule it on the AMD runner, as it has less tests right now.
