backport src definition from 2.16

Browse Source 
This fixes a weirdness when consuming `default.nix` from the 2.15 release branch archive,
where the Nix derivation's `src` store path gets wrapped for some reason:

    "src": "/nix/store/mfa0j89j4f42nrxwxfwqrz0b6m32ih99-fcyq2x0wld440n9jc756vnh93kvjz9ac-source",

This is the only difference to instantiating the Nix derivation from the
repository itself, and prevents a build cache hit.

It doesn't happen on 2.14 (adds `flake-compat`) and 2.16 (uses `cleanSource`).
I suppose this is somehow caused by `flake-compat` doing something funky,
