qemuxml2argvdata: Adjust maximum NUMA node used

We have couple of qemuxml2argvtest cases where up to 8 NUMA nodes
are assumed. These are used to check whether disjoint ranges of
host-nodes= is generated properly. Without prejudice to the
generality, we can rewrite corresponding XML files to use up to 4
NUMA nodes and still have disjoint ranges.
