chore(nix): cleanup (ayamir#1252)

* chore(nix): cleanup

This commit introduced three changes:

1. Opt for a shallow clone whenever we run the `update_flake`
   workflow since there's no need to retrive past commits.
2. Deleted `result` from `.gitignore` bc I couldn't track down its
   source (correct me if I'm wrong!)
3. Ensure either XCode or the CLT is installed on macOS before
   running `otool`. These aren't included by default on a fresh
   macOS install, and using `xcrun` can sort out those dependency
   snags.

* revert(gitignore): add `result/` back
