dns/dnsmasq-devel: update to 2.80test7
Changes since test6, from CHANGELOG:
Change anti cache-snooping behaviour with queries with the recursion-desired bit unset. Instead to returning SERVFAIL, we now always forward, and never answer from the cache. This allows "dig +trace" command to work. Include in the example config file a formulation which stops DHCP clients from claiming the DNS name "wpad". This is a fix for the CERT Vulnerability VU#598349.
