Following #2541 with its quick fix for 16.x, we need a more "in depth" fix for master.

The $_COOKIE['lang'] might have a value coming from any other web application (including other instances of Piwigo) on the same host. We should use Piwigo functions pwg_get_cookie_var and pwg_set_cookie_var to be more restrictive on the accepted path of the cookie.
