make-system-tarball: create reproducible tarballs
Ensure that archive members are added in sorted order with a fixed mtime. This allows `nix-build --check` to succeed (when building a tarball of a simple system configuration). We also remove env-vars which doesn't appear to do much apart from capture a bunch of store paths we probably don't want. This is an alternative to https://github.com/NixOS/nixpkgs/pull/2281/commits/4b78a5b5fb8584347999832b3c67d1276488140b
