The "virt" machine supports disk emulation, so use a ext4 rootfs instead of
initramfs for consistency with the other qemu defconfigs.

Run the emulation with:
- qemu-system-aarch64 -M virt -cpu cortex-a57 -nographic -smp 1 -kernel output/images/Image -append "console=ttyAMA0" -netdev user,id=eth0 -device virtio-net-device,netdev=eth0
+ qemu-system-aarch64 -M virt -cpu cortex-a57 -nographic -smp 1 -kernel output/images/Image -append "root=/dev/vda console=ttyAMA0" -netdev user,id=eth0 -device virtio-net-device,netdev=eth0 -drive file=output/images/rootfs.ext4,if=none,format=raw,id=hd0 -device virtio-blk-device,drive=hd0
The login prompt will appear in the terminal that started Qemu.
