[osg-submissions] Fast oaths

[Paul Martz]

Understood. Well, I think it's reasonable to assume that the non-env var
case is the more tested case, and therefore it is correct to set
_supportsVertexBufferObjects to the same value as _fastPath. So here's a
change that does the same thing for the env var case.
