Title: Update dnsmasq to new version and enable for OS X

I've been using dnsmasq on OS X for quite some time and it works alright, so one of the commits enables the package for OS X. I updated the package to the current dnsmasq version (2.71) while I was at it and also made it use the .xz file instead of the .gz archive since the former is about 30% smaller.
