`pathContentsGood` is used to assess the validity of a path as part of derivation goals *in repair mode*. When repair is used with a diverted store, i.e. a store where fsPath(toRealPath(s)) != fsPath(s) for s a store path, this result in utterly broken behavior because it will attempt to assess the goodness of the *logical* store locations, most of the time: /nix/store/... So, if you are repairing your system using a live NixOS ISO. Your ISO contains a `/nix/store` (assumed to be good) and you repair your system which is rooted at /mnt and contains its own /nix/store, that is, a Nix store at /mnt/nix/store. Performing the following operation `nix-store --verify --repair --store /mnt` will assess the contents goodness of the ISO's Nix store. To avoid this, we assess the path existence of the *physical path*, aka the result of `store.toRealPath` applied to a *logical* store path string representation and we verify the hash of the *physical path*. The error messages are not taken care of in this CL as those are purely cosmetic and helps the user understand what is going on. Fixes #892.
