Jenkinsfile: run check-config.sh to print system configuration

Having this information can help debugging issues in CI (which could
be caused by missing/incorrect configuration of the machines).

We ping to a fixed version of the script, because this script is ran
directly on the host, and we don't want pull-requests modifying this
script to have direct access to the machines.
