[PATCH] Return "404 Not found" if a repo doesn't exist (any more).

If a repository disappears, cgit says "No repositories found" and
returns "200 OK" [to the webcrawler] for pages referring to, say,
commits in the, now, missing repository.

This, slightly awkward, patch makes it return "404 Not found" in this
case. There is probably a better way to do this.
