docker: update to Nix 1.11.14
docker: update to Nix 1.11.14

- Use the latest Nix version 1.11.14.

- Attempts to download the Nix installation tarball from http://nixos.org
  redirect to https these days, which wget doesn't support unless OpenSSL is
  available.

- Use addgroup and adduser commands to create the Nix build users.

- Link the Nix profile script into /etc/profile.d, where it's run
  automatically.

- Dropped installation of bash and tar. Neither tool is essential for running
  Nix.

Use the command "docker build -t nix . && docker run -it --rm nix sh -"
to build and run the Nix docker container.
