fix(jk2): load the server config from GameData/base (#5166)

jk2mvded only execs config files from GameData/base, so jk2server.cfg in
GameData was never loaded and the server ran with defaults ("noname").
servercfgdir now points at GameData/base, and an existing jk2server.cfg in
the old location is moved there.

Fixes #5165
