Relax permissions for cleanup
Relax permissions for cleanup

Issue was that job running inside the container needs to have write
permissions to some dirs. Easiest to achive this is by `chown`'ing
everything to the "jenkins" user inside the container. But then workdir
can't be cleaned up afterwards by "jenkins" user outside the container!

Solution is to chmod a+rwX everything before cleanup.
