actually enable to resize NILFS2

bit of support was there but code could not be reached
also actually include nilfs-resize for resizing NILFS2

It's only supported online:
"This command is valid only for mounted NILFS2 file systems, and
will fail if the device has no active mounts."

Note that ext3/4 could use the same path but only for growing.
XFS could also share that path...
