Subject: [PATCH] home-manager: show full script path on activation error

Run the activation script in its original nix-store location so that
Bash error messages show the real script location instead of 'wrkdir',
which gets deleted right after the script exits.

(cherry picked from commit 02a501705a11f14ddc21a215c01ed3c1c16a007c)
