[libgd] main-icon-view: Use G_ADD_PRIVATE

[Debarshi Ray <debarshir src gnome org>]

commit 504fb2ad08b155a8a775df786948c122d2b46c80

    main-icon-view: Use G_ADD_PRIVATE
    
    This paves the way for improving our GObject use and reducing the
    amount of boilerplate.
    
    G_ADD_PRIVATE was introduced in GLib 2.38, which should be old enough
    for all users.
