This is the approach I have taken, it fixes the test program when
VAO's are used and the array::setBinding(..) is called after the
Geometry::set*Array() call.

I think it's the safest and least intrusive way to catch late calls to
setBinding(..).

Could you all test the OpenSceneGraph-3.6 head and if this works fine
we can start thinking about going for 3.6.2.
