Correctly build extension and package.

- Correctly setup `lib` and `include` dirs with libzim.
- Build sdist only on python 3.6 to avoid duplicate file at upload on pypi
- Build extension with `rpath==$ORIGIN` to allow wrapper to find
  embedded `libzim.so`
- Copy `libzim.so.6` in libzim directory before creating the wheel to
  embedded it.
- Use the `manylinux_x86_64` name for the platform name.
