BulletSim: add check in avatar stair step code to verify the collision

is not with a volume detect object.

This fixes a problem of avatars trying to step over a volume detect object
that they collide with. This appeared as the avatar popping up as it started
to step up but then continuing on since the object wasn't physically interacting.
