    Fix lobby join-locally key not matching the user's actual Use binding

    G_Responder's lobby handling checked ev->data1 against a hardcoded
    ' ' for "join locally", but that's just vanilla's default Use key -
    users can and do rebind it (key_use), and a literal space never
    matches whatever they've actually configured. Check against key_use
    itself instead, so it works with whatever key each player has bound,
    default or not.
