owut: revert rootfs restrictions

Some platforms have mtdblock devices and also store the rootfs on a
resizable partition (one case is octeon/generic:ubnt-usg).  Remove the
code that disables --rootfs-size until such time as we can determine
the device type and size available for the rootfs partition properly.
