Logwatch on virtualized FreeBSD

Hey,

I realized today that Logwatch on FreeBSD is somewhat broken, at least
in terms of network device compatibility. The zz-network service seems
to use `netstat -i | grep -v Name` to obtain available network
interfaces, but on a virtualized FreeBSD system, vtnet is returned,
instead of vtnet0.

I am not a developer, so unfortunately I cannot submit a patch
(theoretically I could but I can't guarantee that it would work), but
wouldn't it make sense to use something like:

ifconfig | awk -F : '{print $1}' | grep -v "^[[:space:]]" | grep -v lo

which returns the available network interfaces minus loopback? I'm sure
this could be made cleaner, this was just a quick oneliner.

I look forward to hearing back.

Some additional info if it helps:

Logwatch 7.4.0 (released 03/01/11)

(ps: this could also be related to the fact that this is an older
version than what is currently available- what I have running now is
just what was in ports. If I should be using a more recent version, let
me know. Thanks!)
