Using the 'uuid' element for ppc64 NVDIMM memory added in the previous patch, use it in qemuBuildMemoryDeviceStr() to pass it over to QEMU. Another ppc64 restriction is the necessity of a mem->labelsize, given than ppc64 only support label-area backed NVDIMMs. Finally, we don't want ppc64 NVDIMMs to align up due to the high risk of going beyond the end of file with a 256MiB increment that the user didn't predict. Align it down instead. If target size is less than the minimum of 256MiB + labelsize, error out since QEMU will error out if we attempt to round it up to the minimum.
