[gtkmm] Gdk::Cursor: Make get_image() and get_surface() const-correct

[Kjell Ahlstedt <kjellahl src gnome org>]

    Gdk::Cursor: Make get_image() and get_surface() const-correct
    
    gdk_cursor_get_image() returns a pointer to a newly created GdkPixbuf.
    gdk_cursor_get_surface() returns a pointer to a newly created cairo_surface_t.
    get_image() and get_surface() can be const methods, and return non-const
    Gdk::Pixbuf and Cairo::Surface.
