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.
Avoid using strlen as that will break on none null terminated buffers.
