Retire support for "haskellPackageOverrides" from the Nixpkgs config file.

54baa53 added support for the special attribute "haskellPackageOverrides" to the Nixpkgs config file to which users could add their Haskell-specific package overrides. That mechanism has since then been replaced by the more general "packageOverrides", which has subsequently been replaced by Nixpkgs overlays, which have recently been extended for Haskell-specific needs by the "haskell.packageOverrides" attribute. "haskellPackageOverrides" was never documented anywhere, so it seems unlikely that its removal is going to affect anyone.
