initramfs-framework: support ro boot parameter
Default is to mount the rootfs read/write. "ro" can be used to turn
that into read-only, which is useful on systems where userspace does
an fsck before remounting read-write.
Giving both "ro" and "rw" will still mount read-only regardless of the
order, because the ordering information is not preserved by the
initramfs-framework's boot param support.
