Update shell.nix

According to
https://nixos.org/manual/nixpkgs/stable/#sec-darwin-legacy-frameworks,
the darwin.apple_sdk.framework namespace has been deprecated.

This commit updates shell.nix to be compatible with the nixos-unstable
channel on darwin. Tested by running `nix-shell --pure` and then `make`
inside that shell.
