fix(sdtd): read telnet password into telnetpassword (#4968)

fn_info_game_sdtd stored TelnetPassword in ${telnetpass}, but
command_stop.sh, info_messages.sh and the localhost check in the same
function all read ${telnetpassword}. The graceful telnet shutdown never
sent the password, and the telnet IP was always forced to 127.0.0.1,
so stop fell back to killing the tmux session without a world save.

Fixes #4957
