* cache: default to DNSSEC

This change does away with the DNS/DNSSEC distinction the cache
currently makes. Cache will always make coredns perform a DNSSEC query
and store that result. If a client just needs plain DNS, the DNSSEC
records are stripped from the response.

It should also be more memory efficient, because we store a reply once
and not one DNS and another for DNSSEC.
