linux agent reports only active networks

Ocsinventory-Agent-1.1.2 in Linux currently only reports network interfaces that have an IP address.
This can really limit reporting on WLAN & Ethernet connections

I am using the following minor changes to /lib/Ocsinventory/Agent/Backend/OS/Linux/Network/Networks.pm

:88
- if ($line =~ /^$/ && $description && $ipaddress) {
+ if ($line =~ /^$/ && $description && $macaddr) {

:154
- $description = $driver = $ipaddress = $ipgateway = $macaddr = $pcislot = $status = $type = $virtualdev = undef;
+ $description = $driver = $ipaddress = $ipmask = $ipgateway = $macaddr = $pcislot = $status = $type = $virtualdev = undef;

I've modified line 154 as the ipmask was not being cleared between reading interfaces. This just meant that if an interface did not have an ipmask (ie. no IP) it could take on a mask of another interface

Thanks,
Michael
