  refactor: make util an object library
  
  Instead of simply including the utility files directly, make them a
  cmake object library for easy reusability between other projects within
  libgit2.
  
  Now the top-level `src` is responsible for platform selection, while the
  next-level `libgit2` and `util` configurations are responsible for
  identifying what objects they include.
