python3-setuptools: Update to version 68.2.2-1

- IPFire-3.x
- Update from version 65.6.3-1 to 68.2.2-1
- arches = noarch had to be removed otherwise the build came up with the error message that
   python3-setuptools could not be built for x86_64 and failed. Removing that line allowed
   the build to complete successfully. All the other python3 packages that I checked did not
   have that line in them.
- The source_dl line required a change for the new version as the url is not maintained with
   the same structure for each version.
- Changelog is too large to include here. Details can be read at the following link
