    compositor: rebuild the global list if we've removed a surface from it

    The list of surfaces used by weston_compositor_pick_surface() is
    maintained in list of surfaces stored on the compositor. This list is
    generated from the surfaces across all the layers using
    weston_compositor_build_surface_list.

    When destroying a surface the surface is "unmapped" with
    weston_surface_unmap which removes it from the layer list. However since
    the compositor surface list was only being rebuilt when the output was
    repainted a call to weston_compositor_pick_surface before the next
    output repaint would use an outdated surface list containing surfaces
    that have been partially destroyed.
