tasks: Switch run-local.sh to testing logs in S3

https://github.com/cockpit-project/bots/pull/3403 switches tests-scan
over to log to S3. Adjust run-local.sh's test_pr() for that. Create a
separate "logs" S3 bucket to mimic what happens in production.

Drop checking the "status" file, as the S3 stream does not do this.
