Load extra variables correctly in wrapper

The extra variables are meant to be loaded contextually if ansible
or ansible-playbook are executed in the OSA playbooks dir, or if the
openstack-ansible wrapper is explicitly called.

This is occurring correctly for openstack-ansible and ansible-playbook,
but extra vars are not being loaded correctly (despite being output
to console as if they're being loaded) when ad-hoc ansible commands
are run in the OSA context.
