Prefer builtins.path
Following the advice of Domen's nix.dev anti-patterns, I'm preferring something
like...

```nix
builtins.path { path = /path/to/some.where; name = "some.where"; }
```

...to

```nix
/path/to/some/where
```

While the former is more verbose, it will fail to build when the path doesn't
exist, which I prefer.
