/* Terrible backward compatibility hack to get the path to Nixpkgs
from here. Usually, that's the relative path ../... However,
when using the NixOS channel, <nixos> resolves to a symlink to
nixpkgs/nixos, so ../.. doesn't resolve to the top-level Nixpkgs
directory but one above it. So check for that situation. */
