tests: Add qemuxml2argv tests for PPC64 pseries machine

Add four tests of the XML -> argv handling for the PPC64 pseries machine.

The first is just a basic test of a bare bones machine.

The three others test various aspects of the spapr-vio address handling.

It seems that currently we can't include network devices, doing so leads
to a segfault because the network driverState is not initialised. Working
around that leads us to the problem that the 'default' network doesn't
exist. So for now just leave network devices out.
