Enable new SELinux boolean for vTPM support

In order to get a working vTPM support in containers, we need to enable
a new SELinux boolean provided by openstack-selinux[1].

This patch affects only the deprecated
nova-libvirt-container-puppet.yaml template in order to do a clean
backport to stable/Wallaby and stable/Victoria.
