stdlib: Update the stdlib resource downloader for versions

The 'resources.json' file in gem5 resources is used to lookup resources.
The stdlib resource downloader was hardcoded to the 'resources.json'
stored in the gem5 resources stable branch. This change allows the gem5
downloader to obtain the specific resources.json.
