Ironic containers: chown /var/lib/ironic correctly

This updates the docker version of ironic-conductor.yaml so
that it sets permissions on the entire /var/lib/ironic
tree correctly. Since 1a4ece16ce
we bind mount in /var/lib/ironic from the host (created via
Ansible if it didn't already exist). This caused a subtle
permissions issue in that the Ironic conductor service
can no longer create sub-directories it needs to operate.
