[ssu] Use cached SystemBus connection for ssu-queries. MER#1694
If ssu functionality is called in inappropriate state of usb-moded
startup, it will implicitly make SystemBus connection.

Use cached cached connection, so that attempts to make ssu queries
will fail (with error logging) if they done before the main logic has
connected to the SystemBus.
