KNXnet/IP NSE Update and Service Probe

[Niklaus Schiess <nschiess () adversec com>]

Hi,

I've updated the  knx knx-gateway-info.nse (see attached file) [1]. It
fixes two printing issues and will now work in NAT environments.

Additionally I've created a service probe. KNXnet/IP gateways saeem to
support using '0.0.0.0' as source IP for the Description/Connect
requests, instead of the actual client address. In this case they will
just use the source IP and port which allows to write a simple probe.
The probe sends a Description request which is static. The response's
header is also static, so this should be quite reliable. I've attached a
patch for the service probe as well.

Regards,
Niklaus
