Try to update haskell.nix, iohk-nix (and via those → Nixpkgs)

[michalrus]

I encountered a problem – after Darwin CI update to Monterey, this code no longer compiles (actually, on anything ≥ Big Sur), failing with:

…
[2 of 2] Compiling Data.ByteString.Base16.Lazy ( Data/ByteString/Base16/Lazy.hs, dist/build/Data/ByteString/Base16/Lazy.o )

This is a known error that happens in older Nixpkgs. So we need to update Nixpkgs (indirectly).

• I took haskell.nix and iohk-nix revisions from https://github.com/input-output-hk/cardano-wallet/tree/3c5f99384f16dd2af7a65528c19e5fec72d0a5cc/nix
• @hamishmack provided a working cabal.project
• I fixed compilation errors
• But some tests are still failing…
• nix-build -A cardano-launcher works, so I’m probably good w.r.t. what Daedalus needed (QA will verify there)…
• … but we need to proceed with this update… somehow,
• also, @angerman says iohk-nix may be abandonware, so I guess we should get rid of this dependency? Although it has recent commits.
