This fixes an error on installing ufo3k branch. ufoLib files are already removed in #68.

What library is still relying on this particular branch? Shouldn't the robofab/ufo3k branch be deprecated, now that ufoLib is a standalone package, and fontParts is being developed?

Shouldn't the robofab/ufo3k branch be deprecated,

Oh, I didn't know that. Thanks. I was trying to install ufo3k branch just for my small script.
