chore(3p/nix): don't rebuild nix-proto-srcs as much r/1380
Interpolating a path into a string will copy the referenced path into the Nix store, so this got a dependency on all of src. By first constructing a path to the src/proto directory using the + operator, and then interpolating it, we limit what is copied to the store, and therefore what code triggers a nix-proto-srcs rebuild.
