asterisk: dnsmasq.conf: Avoid forwarding queries to other DNS servers

This creates problems when requesting resolution of the IPv6 address.
For some reason, dnsmasq was forwarding the request to the non-available
google DNS servers, and Asterisk docker container pre-start commands
checking for DNS resolution would never pass when run in jenkins node.
