CachedDownloadResult: Include store path

Also, make fetchGit and fetchMercurial update allowedPaths properly.

(Maybe the evaluator, rather than the caller of the evaluator, should
apply toRealPath(), but that's a bigger change.)

(cherry picked from commit 5c34d665386f4053d666b0899ecca0639e500fbd)
