nix-profile.sh: Revert to single-user version
Commit 6a214f3e06fa1c5f0a4d40e555f14d87691af297 copied most of the Nix
shell initialisation code from NixOS to nix-profile.sh; however, that
code assumes a multi-user install and is Linux-specific (e.g. it calls
the "stat" command).  So go back to the simple single-user version.

Fixes #49.
