udev: allow persistent storage rules for zram devices

The /dev/zramN devices can be used as regular block devices. They are
typically used for swap areas, but it would be beneficial to have
LABEL and UUID in the udev database to make it more user-friendly for
tools such as lsblk or mount (if used with other filesystems).
