fix TriangulateInPlace to work with latest FBX Python SDK 2015.1 (#9379)

TriangulateInPlace is deprecated and throws an error with FBX Python SDK:
http://usa.autodesk.com/adsk/servlet/pc/item?siteID=123112&id=10775847

Need to use `bool Triangulate(FbxNodeAttribute pNodeAttribute, bool pReplace)`
instead:
