scripts: ubinize-image: make rootfs optional

Browse Source 
Currently ubinize-image script always expects the
rootfs image to be passed and a volume for it created.

So, to allow only ubinizing a kernel for example which
the MikroTik hAP ac3 and other new NAND devices from
MikroTik require make rootfs an optional parameter like
kernel.
