            Log:
            add new test dedicated to systemd-bootchart

The systemd-bootchart service is confined by SELinux policy.
Unfortunately, the behavior of systemd-bootchart program
differs from what SELinux policy defines as allowed.

This test case covers various interactions of systemd-bootchart
and SELinux.
