build: remove haskell related nix code and haskell.nix dependency
* Upgrades the nixpkgs pin to 21.11.
* Removes nix code, sources, and attributes related to haskell.nix and
  the code under pkg/hs.
* Continuous integration no longer builds (or packages/releases)
  urbit-king (haskell).
* To continue to developing any haskell code under pkg/hs it's left as
  a user exercise uto install and configure GHC/Stack.

As a consequence running nix-shell should be considerably more
performant and requires downloading or building less dependencies.
