support .originalSrc attr as a fallback

[abathur]

If a builder creates a sequence of derivations on the way to building a package, nixpkgs-update won't be able to find the
correct src attr to query. We can technically use passthru to lie about the src, but src is load-bearing and this may
mislead or confuse humans (or other tools?) later.

This change checks an originalSrc fallback attr that isn't load-bearing within builds or nixpkgs.

If I can get a little guidance on where they should be documented and whether you'd like them in one or multiple PRs, I'd also like to follow up with one or more PRs to at least partially document:

1. Which derivation attrs nixpkgs-update uses (including this new one).
2. Document the macOS blocker in running update yields 'openFile: does not exist (No such file or directory)' error on macOS #323 if I can't find someone else who has it working there.
3. Better document filesystem preconditions:
   • setting up the github/hub auth token
   • if we use an existing local nixpkgs checkout, it looks like it needs to have an upstream remote that has been fetched

Looks fine. Thanks!
