Cirrus: Add Second partition for storage testing

This is mainly/initially to support use of Cirrus-CI
in https://github.com/containers/buildah since that setup
re-uses the VM images from this project. However, it also
opens doors here, if libpod ever needs/wants to do things
with a dedicated storage device and/or storage-drivers.
