Default all container storage to /var/lib/containers/storage

containers/storage is defaulting to /var/lib/containers/storage
for image and containers storage.  It is also defaulting to
/var/run/containers/storage for all runtime.  The defaults
for CRI-O should match so that lots of other tools that use
containers/storage can share the same storage.
