* At build-time, Git is used to see if the build is inside a Git repo and if so, git info
  is added to the build information that Elixir returns with `System.build_info()`. The code
  uses PATH + `git` so the Git version from the inputs is used which is just fine.
* At run-time, Git is used by Mix if, and only if, there are any Git-based dependencies. This
  is not the normal case, and in that sense Git is an optional dependency of Elixir - most
  projects will work just fine without Git being present. Here, too, PATH + `git` is used
  so if there is a need on a user's system to use Git-based dependencies, the user can just
  add the package to the profile and things will just work.

I feel that leaving this alone is cleaner than trying to fix the dependency (if we want to
keep it, it needs to be in propagated-inputs in order to keep Git around; I stumbled upon
this building a project with Git dependencies after doing a `guix gc`. However, given that
using Git dependencies is the exception and I think that minimizing dependencies is nicer
I opted to just remove the substition completely).

* gnu/packages/elixir.scm (elixir)[arguments]: In 'replace-paths' phase,
remove substitutions of "git".
