mesa/st: Fix piglit read-front with new drawable invalidation v2
When the state tracker adds a front buffer, nothing triggers a validate
drawable call, since the state tracker manager is never notified.
Force a validate drawable call by invalidating the framebuffer's stamp, so
that the window system's renderbuffer (if any) is picked up.
This fixes bug 38988
