image_types: Ensure /init exists for cpio rootfs archives
In order for the kernel to accept an initramfs as a rootfs,
it must have /init - even if it is an empty file. Touch /init
to ensure it exists for cpio and cpio.gz image types.
When used with initrd and rootfs=/dev/ram0, this allows the
cpio and cpio.gz images to be used as the rootfs.
