fix(col): monitor Colony Survival with a TCP query (#4977)
* fix(col): monitor Colony Survival with a TCP query
Colony Survival hosts with SteamOnline networking and doesn't answer
A2S (protocol-valve) queries on its UDP game port. Monitor always
failed the query and restarted a working server every few minutes.
The query port listens on TCP (details already shows it as TCP), so
use query mode 5 (TCP).
* fix(col): keep querytype set for the gamedig query modes
querytype is ignored by the TCP query, but an empty value would break
monitoring if querymode is switched back to a gamedig mode.
