Serves a sub-path of a package directory for the package with hash meta_far on server_end.

The connection rights are set by flags, used the same as the flags parameter of fuchsia.io/Directory.Open. On error while loading the package metadata, closes the provided server end, sending an OnOpen response with an error status if requested.
