qemuxml2argvtest: Update 'aarch64-virtio-pci-manual-addresses' case

With all supported qemu versions we'll pick PCIe to use for the implicit
address busses (those lacking an explicit controller) and thus the
addresses must reflect that.

Update the test to add the new flags, and fix the addresses.
Additionally add a real-caps version of the test.
