nix: update to ghc 9.6.4 (#1927)

* nix: s/pkgconfig/pkg-config/

This alias is deprecated and removed in newer versions of nixpkgs, so just go
ahead and get rid of it and use the proper spelling.

Change-Id: I793f11948bd47be080c5cf6e17c401f168bc68b4

* cabal: update `rocksdb-haskell`

Change-Id: I014a3fb49b0e121bcac4593faff8f4ddea828bd9

* nix: ghc964 update

This includes an update to the IOHK cache signing key, since apparently they're
publishing new binaries under a new key.
