st/mesa: fix geometry corruption by always re-binding vertex arrays

This is a temporary workaround. It fixes sauerbrauten with shaders enabled.

I guess we might be changing vertex attribs somewhere and not updating
the appropriate dirty flags, therefore we can't rely on them for now.
Or maybe we need to make this state dependent on some other flags too.
