Add opensubdiv/version.cpp

This empty cpp file is added to address some cmake dependency resolution issues
with XCode project-based build generation.

I may add some functionality to version.cpp in the future

Thanks stopiccot for investigating the issue and doing most of the leg-work.

fixes #356
