Matthew Bauer 7c20ee448f Sync NIX_PROFILES between single-user and multi-user modes
When we are in single user mode, we still want to have access to
profiles. This way things in Nixpkgs that rely on them getting set
accurately are done in both cases. The point where I hit this is with
using aspell which looks in NIX_PROFILES:

https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/aspell/default.nix

Before this patch, NIX_PROFILES was never set in single user mode!
This corrects that.
