We don't want mirror.pkgbuild.com's DNS server to be a single-point-of-failure, so this commit adds multiple authoritative DNS servers for the zone. The extra DNS servers are run on the geomirror servers.
The _acme-challenge zone, used for obtaining certificates, is run solely on mirror.pkgbuild.com's DNS server, to avoid syncing DNS records between the servers (KISS).
