resolved: port ResolveRecord() bus call implementation to dns_resource_record_to_wire...

Now that we have dns_resource_record_to_wire_format() we can generate
the RR serialization we return to bus clients in ResolveRecord() with
it. We pass the RR data along in the original form, not the DNSSEC
canonical form, since that would mean we'd lose RR name casing, which is
however important to keep for DNS-SD services and similar.
