Use GtkMenuPositionFunc you get coordinates of pointer with respect
to root.  Then use gdk_window_get_origin() to get the button's GdkWindow
coordinates with respect to root.

void menu_position_function (GtkMenu  *menu,
                             gint     *x,
                             gint     *y,
                             gpointer  data)
{
    GtkWidget *button = GTK_WIDGET (data);
    gint wx, wy;

    gdk_window_get_origin (button->window, &wx, &wy);
    *x = wx + button->allocation.width / 2;
    *y = wy + button->allocation.height;
}

 ...

    if (event->button == 3) {
        gtk_menu_popup (GTK_MENU (popup_menu),
                        NULL,
                        NULL,
                        menu_position_function,
                        button_widget,
                        event->button,
                        event->time);
        return TRUE;
    }
