qemuxmlconftest: Introduce memory-hotplug-nvdimm-overlap test case

This new test case checks whether we are handling NVDIMMs
correctly when checking for overlapping memory devices (see
previous commit). Without previous commit, this test case would
fail, yet it was produced in real life (at least the NVDIMM
part) and thus it is valid.
