Avoid the ``ruptime: no hosts in /var/rwho.'' message by not calling

rwho iff /var/rwho is empty.  Call `uptime' instead.  This doesn't
belong under `network' right away, but at least reports the same
informaton about the local system.  rwhod is not turned on by default
(for good reason), and i've already seen too many of the above
messages...
