lib: add shortcuts for fake hashes (fakeSha256, fakeSha512)
Fake hashes can be used as placeholders for all the places, where Nix expression requires a hash, but we don't yet have one. This should be more convenient than following: - echo|sha256sum, copy into clipboard, go to editor, paste into previously edited place - search nixpkgs for a random package, copy it's hash to cliboard, go to editor, paste into previously edited place Nix can add support for these fake hashes. In that case printed error should contain only 1 hash, so no more problem "which of two hashes from error should I use?" Idea by irc:Synthetica
