Always explicitly create QEMU system containers upfront.

This is where I would expect 'backend' to have been created
rather than ui/console.c, though you could potentially make
a case to create it from the machine function, snice console
stuff can't be used outside of the machine context, while
chardevs/objects can be used in qemu-img/qemu-nbd, etc
What about creating "backend" container in qemu_create_machine()?
