[xdg-user-dirs-gtk] Make the 'Don't ask again' checkbox work properly

[Matthias Clasen <matthiasc src gnome org>]

commit 9c19d7fedadf38cc4fec21efdb3908572448f658

    Make the 'Don't ask again' checkbox work properly
    
    We used to remove the user-dirs.locale file when this is checked,
    but that prevents xdg-user-dirs-gtk-update from ever running again.
    Instead, update it with the current locale. This has the effect
    of keeping xdg-user-dirs-gtk-update from running until the locale
    changes again, which is probably closer to the intended effect.
