Use pkg.in/src-d/go-git.v4/ for Git indexing

This library is written in pure Go, so:

* it simplifies compilation and deployment

* no more memory leaks due forgotten Free() calls

* potential for lower memory use in large superprojects, since
  Repository objects don't have to be Free()d individually.

This comes at the cost of a 30% end-to-end slowdown indexing the
Gerrit repo.
