/etc/network.subr list_net_interfaces() fix

[Chris Csanady <cc@xxxxxxx>]

By the time list_net_interfaces() is called in /etc/rc.d/netif,  
clone_up() has
already created each of $cloned_interfaces.  At this point, they will be
shown by the 'ifconfig -l', so there is no need to explicitly append  
them.
In doing so, the cloned interfaces are configured and listed twice.

clone_up() is called from network_start(), before network_common() in
/etc/rc.d/netif.  list_net_interfaces() is only called from  
network_common()
and /etc/rc.d/dhclient, which is itself dependent  on netif.	Therefore,
appending the cloned interface list here will always result in  
duplicates.
