gnome: fix Home Manager activation (#860)

Browse source 
This suffers from the same issues as the KDE activation:

- The program is not available in $PATH, but should not be installed for
  all users.

- The program only works when GNOME Shell is running.

Therefore, we use a very similar solution.
