This fixes a problem where ctld would refuse to start on boot
with an IP address to listen on configured in ctl.conf(5).
It also fixes a problem where ctld would fail to start with
some network interfaces requiring a sysctl.conf(5) tweak to
configure them, eg to switch them from InfiniBand to IP mode.
