Test with internal Jenkins in parallel

Attempt osbuild testing on the internal Jenkins deployment with
nodes that are destroyed after each use. The internal Jenkins looks for
a Jenkinsfile inside the `schutzbot` directory.

Let's not remove the `jenkins` directory (used by jenkins.osbuild.org)
yet until we know the internal Jenkins is stable and performs well.
