Subject: [PATCH] home-manager: make sure Nix profiles path exists

The Nix profiles path may not exist right after installing Nix. In
that case, it is created on demand by the Nix CLI tools. However, Home
Manager assumes it exists and fails if it doesn't.

This change makes sure to trigger the creation of the Nix profiles
path before attempting to access it.
