Easily install Nix in a Qubes VM.

Qubes virtual machines are usually based on templates and make it hard to have a persistent Nix installation (surviving restarts). This is hard because Nix assumes the directory /nix as the place to store all nix artefacts. There does not seem to be an easy option to change the default path in Nix.

/nix is defined as a bind-dir in the Qubes VM. The installer then installs Nix in single-user mode.

There is no "uninstall" defined (yet).

1. Create a new virtual machine in Qubes
2. Download the installation script (it is self-contained)
3. Run the installation script
4. Run source ${HOME}/.profile to load the environment
5. Run nix --version to verify that nix is installed

Pull Requests are preferred.
