give the ext4 image a disk label
- this allows the kernel cmdline and fstab to refer to it by label
instead of by /dev/sda or /dev/vda (depending on whether the disk is
attached to qemu via virtio or not)
- it allows other consumers of the image to detect that this is an
image created by debvm and then treat it accordingly
