stdlib: Update the resources.json URL

It is important this URL remains stable across releases. Pulling
directly from the Google Source git repo is not stable and may change
over time. This patch updates the URL to
https://resources.gem5.org/resources.json. As the gem5.org domain is
under the gem5 project's control, we can ensure this does not change.
