resolved: correctly handle non-address RR types with /etc/hosts lookups (#4808)
Fix wrong condition test in manager_etc_hosts_lookup(), which caused it to return an IPv4 answer when an IPv6 question was asked, and vice versa. Also only return success if we actually found any A or AAAA record. In systemd-resolved.service(8), point out that /etc/hosts mappings only affect address-type lookups, not other types. The test case currently disables DNSSEC in resolved, as there is a bug where "-t MX" fails due to "DNSSEC validation failed" even after "downgrading to non-DNSSEC mode". This should be dropped once that bug gets fixed. Fixes #4801
