fix teeworld server query, #3

Hi, this fixes the Teeworlds server query, it tries with the 3 known `getinfo` packets.

I renamed the `-tee` argument to `-tees` since I will work next on the `-teem` Teeworlds master query.

Since Teeworlds support was broken since many years, there is probably nobody that uses the `-tee` arg today.
In order to avoid unessaary indetation its often better to deal with the error case early by inverting the test.

Also in this case you may run off the end of the packet we that's not been pre-validated to ensure there's enough data.
