x86: use PARTUUID instead explicitly specifying the device by default
This changes the x86 image generation to match x86_64, using the PARTUUID for the rootfs instead of explicitly configuring the device. It unbreaks KVM with VirtIO, which uses /dev/vda2 instead of /dev/sda2. Tested in QEMU/KVM with VirtIO, VirtualBox and VMware.
