The daemon-reload, service restart, and service check tasks in
service.yml, prune.yml, update_runner.yml, and integration_test.yml
were not guarded by docker_rootless_setup. In CI containers without
a systemd user bus, these tasks fail with "Failed to connect to bus".
Also fix the integration_test.yml validation task to not fail on
service status when docker_rootless_setup is false.
