resolved: make outselves authoritative for /etc/hosts entries in full
If you query for an MX RR of a host listed in /etc/hosts, let's return
an empty reply rather than NXDOMAIN, i.e. indicate that the name exists
but has no MX RR assigned, thus making ourselves authoritative.
The venerable "host" tool by default sends requests for A + AAAA + MX
and ensures we never propagate queries further on.
Fixes: #31223
