Summary: Mangling `sys.path` in `.py` tests could break tests running with `buck` opt build. Because the bundled extensions won't be used, but files in the working copy will. It's okay-ish for pure Python extensions. But native extensions will have problems. Reviewed By: ryanmce Differential Revision: D6974954 fbshipit-source-id: 8a7f3d86e5c2fbf16cfcc971743d99585fe61b99
