Remove unused DEPLOY_AIO variable

Commit https://review.openstack.org/#/c/411406/ exposed the fact that
the run-playbooks.sh script wasn't making use of the DEPLOY_AIO variable
in a useful way, and as a result, the script is exiting without building
an AIO.

This patch removes the dependency on that variable.
