bifrost: bifrost-provision.sh: Always initialize XCI_ANSIBLE_VERBOSITY

The XCI_ANSIBLE_VERBOSITY is normally exported by the XCI bootstrapping
process. However, sometimes it's necessary to run bifrost-provision.sh
by itself so we can debug machine provisioning. As a result of which,
we need to initialize this variable properly so we don't fail with
'unbound variable' errors.
