Upstream-Issue: NixOS/nix#9319

Describe the bug

Whether the current store (or configuration (#9318)) enables the case hack should not affect the language.
Nix tries to support case sensitivity as much as possible, including allowing case sensitive paths to be represented in the store. This does not need to be detectable and arguably should not be detectable.

Steps To Reproduce

One a store (or machine (#9318)) that has the case hack, run nix repl

> :lf nixpkgs
> builtins.readDir (legacyPackages.aarch64-linux.ncurses + "/share/terminfo")  
{ "1" = "directory"; "2" = "directory"; "3" = "directory"; "4" = "directory"; "5" = "directory"; "6" = "directory"; "7" = "directory"; "8" = "directory"; "9" = "directory"; A = "directory"; E = "directory"; L = "directory"; M = "directory"; N = "directory"; P = "directory"; Q = "directory"; X = "directory";
  "a~nix~case~hack~1" = "directory"; b = "directory"; c = "directory"; d = "directory"; "e~nix~case~hack~1" = "directory"; f = "directory"; g = "directory"; h = "directory"; i = "directory"; j = "directory"; k = "directory"; "l~nix~case~hack~1" = "directory"; "m~nix~case~hack~1" = "directory";
  "n~nix~case~hack~1" = "directory"; o = "directory"; "p~nix~case~hack~1" = "directory"; "q~nix~case~hack~1" = "directory"; r = "directory"; s = "directory"; t = "directory"; u = "directory"; v = "directory"; w = "directory"; "x~nix~case~hack~1" = "directory"; z = "directory"; }

Expected behavior

The language uses a file system accessor that unapplies the case hack on trees that implement case sensitivity using the case hack.

nix-env --version output
