Return SRV records more inline with the real SRV records


With:

```
set TARGETACTION BYPASS
set TARGETDOMAIN *.google.com
set TARGETHOST 1.2.3.4
```

When I query for the Jabber SRV record, I can confirm that the results in BYPASS mode are identical (enough) to what I'd get if I hit another non-fake DNS server


Real:
```
~ $ dig srv _jabber._tcp.google.com @4.2.2.1 +nostats +noquestion 

; <<>> DiG 9.8.1-P1 <<>> srv _jabber._tcp.google.com @4.2.2.1 +nostats +noquestion

Fake:
```

```

With:

```
set TARGETACTION FAKE
set TARGETDOMAIN *.google.com
set TARGETHOST 1.2.3.4
```

You can see that we get one SRV record as well as an A record to hopefully prevent the subsequent A record lookup:

```
~ $ dig srv _jabber._tcp.google.com @localhost +nostats +noquestion 

; <<>> DiG 9.8.1-P1 <<>> srv _jabber._tcp.google.com @localhost +nostats +noquestion
