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 unnecessary indentation its often better to deal with the error case early by inverting the test.

I agree with that, I have only extended the existing code to minimize the diff.

> 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.

I agree with that but this code written by someone else was accepted before without all this details.

> Oh and the test is back to front in terms of style, should be memcp(...) == 0.

I agree with that, but this part was not written by me.
