GetInterfaceInfo bug fix to make it look at all interfaces

[Tod Oace]

Greetings cfengine maintainers,

I ran into a problem where cfagent (2.0.7p3) wasn't finding any 
interface information on a machine whose "netstat -in" output looks 
like:
# netstat -in
Name  Mtu   Network         Address            Ipkts Ierrs    Opkts 
Oerrs  Coll
ni0*  0     none            none                   0     0        0     
0     0
ni1*  0     none            none                   0     0        0

0  9832

I did some debugging and discovered that GetInterfaceInfo only looks at 
the first interface because it isn't advancing its ifp pointer. This 
might also explain the problem that someone was having with cfengine 
only paying attention to the loopback interface.

The following patch solved my problem:
