With the latest OL7.2, selinux policy that is shipped
might not be the latest for it to work or build with
selinux policy for docker-1.12.
To be able to achieve that here is what is done:
1. Added systemd_machined policy which is part of systemd.
2. Temporarily comment out unconfined_typebounds because the
current OL7's selinux doesn't have unconfineduser selinux policy,
to include this will be too much. Will revisit this once we have
updated the selinux policy.
