bus/driver: Containers can't use the Verbose and Stats interfaces

These are debugging interfaces, which are essentially read-only.
By default, Verbose is not available on the system bus at all and
Stats is only available to uid 0, but both are available on the
session bus, and they can be allowed for other uids by configuring
the system bus.
