290252 by ngie:
Rename etc/periodic/daily/430.status-rwho to periodic/daily/430.status-uptime

The command was checking local/remote system uptime, so rename the script to
match its function and to avoid confusion

The controlling variable in /etc/periodic.conf has been renamed from
daily_status_rwho_enable to daily_status_uptime_enable.

Conditionally install (if_)?(otus|rsu).4, otusfw.4, rsufw.4, and urtwn.4 if
MK_USB != no

Add the manpages to OptionalObsoleteFiles.inc

As a side-effect, this also fixes installworld with MK_USB == no
