[core]: fix query string handling in li_vrequest_redirect_directory (dirlist, index)

- use decoded path instead of orig raw path (which includes the query
  string); the decoded path should be safe, and we also really don't
  need to support any "raw" handling - we're at the filesystem level
  anyway.
