            Log:
            test if policy rebuild affects layered containers

Following error messages appeared when 2 containers (one derived
the other) both manipulate the SELinux policy store:

  libsemanage.semanage_commit_sandbox: Error while renaming
  /var/lib/selinux/targeted/active to /var/lib/selinux/targeted/previous.
  (Invalid cross-device link).
  semodule:  Failed!
  Error: error building at STEP "RUN semodule -B": error while running
  runtime: exit status 1

Purpose of this automated test is to find out if this situation still
happens or not.

The TC covers BZ#2068085.
