nixos/eval-config: Remove NIXOS_EXTRA_MODULE_PATH

Browse Source 
This removes the previously depricated NIXOS_EXTRA_MODULE_PATH
environment variable.

Tested with
$ nix-instantiate nixos/lib/eval-config.nix --arg modules '[{fileSystems."/".device="x";boot.loader.grub.enable=false;}]' -A config.system.build.toplevel
$ NIXOS_EXTRA_MODULE_PATH=$HOME/whatever.nix nix-instantiate nixos/lib/eval-config.nix --arg modules '[{fileSystems."/".device="x";boot.loader.grub.enable=false;}]' -A config.system.build.toplevel

The NIXOS_EXTRA_MODULE_PATH environment variable is deprecated and will be
removed in NixOS 25.05.
We recommend a workflow where you update the expression files instead, but
if you wish to continue to use this variable, you may do so with a module like:
{
imports = [
(builtins.getEnv "NIXOS_EXTRA_MODULE_PATH")
];
}
This has the benefit that your configuration hints at the
non-standard workflow.
