[gdm/wip/release: 3/4] session: pass all language vars through to worker

[Ray Strode <halfline src gnome org>]

    session: pass all language vars through to worker
    
    Right now we set LANG based on the value of setlocale(),
    and disregard all other language environment variables.
    
    This commit just passes the environment variables through
    wholesale.
