This issue should be completely fixed now (after commit 092dd65¹).
(Just to remind) the original issue is a request for auto-finding emacs
packages installed globally (in a system profile).

So, if you update your Emacs, it should automatically find emacs
packages (magit, etc.) installed both in user and system profiles.

To update Emacs, one need to:

1. If emacs is installed in a user profile:

  $ guix pull
  $ guix package --upgrade=emacs

2. If emacs is installed in a system profile:

  # guix pull
  # guix system reconfigure
