Don't register with avahi if KISSPORT is disabled

[ghulands]

I have a setup where i'm using only an igate to publish weather data so I have in my config the kiss and agw ports set to 0. The logs show that it still registers with avahi with port 0.

LOGDIR /var/log/direwolf-wx/
ADEVICE null null

CHANNEL 0
MYCALL N0CALL-13

KISSPORT 0
AGWPORT 0

IGSERVER noam.aprs2.net
IGLOGIN N0CALL-13 12345
IGFILTER  t/m/N0CALL-13/1
# send weather info over igate
PBEACON sendto=IG delay=1 every=5 symbol="weather station" lat=XX.XXXXX long=XX.XXXX commentcmd="curl --silent http://wx/wxnow.txt | tail -1"

Registering to avahi should only happen when the KISSPORT > 0.

I just found the PR where the port check is there, but it doesn't seem to work.

I worked out from the code a work around by having in the config

DNSSD 0
