This looks like a revert of #5844, but is not. That one was needed because https://github.com/NixOS/nix/commit/d90f9d4b9994dc1f15b9d664ae313f06261d6058#diff-0f59bb6f197822ef9f19ceae9624989499d170c84dfdc1f486a8959bb4588cafR85 changed the type of the argument to `allowPath` from a `StorePath` to a `Path`. But since https://github.com/NixOS/nix/commit/caabc4f64889d5a4c47d6102b3aa1d3c80bbc107#diff-0f59bb6f197822ef9f19ceae9624989499d170c84dfdc1f486a8959bb4588cafL100-R92, it is a `StorePath` again. I think this is worth changing because we want to be very careful about `toRealPath` and the evaluator --- ideally the choice of real path does not affect evaluation at all. So using it fewer times is better.
