home-manager: set profile path variables lazily

Browse source 
We only need the Home Manager path variables when performing a few
operations, so only set the variables for those operations.

This avoids problems on fresh installations, where no profile
directory exists.

Fixes #4403

(cherry picked from commit ae896c810f)
