Bug Description

use host uuid on kvm on power too

On power, the qemu uuid is exposed as /sys/firmware/devicetree/base/vm,uuid and should be used like /sys/class/dmi/id/product_uuid is used on x86.

On s390x it only uses sysinfo for systemd-detect-virt,
  src/basic/virt.c:306: r = get_proc_field("/proc/sysinfo", "VM00 Control Program",
  WHITESPACE, &t);

but there also the Host UUID is exposed:
  $ cat /proc/sysinfo
  VM00 UUID: 0804001f-c45f-4345-994f-9fec048e822e

There it also seems not used to (re-)generate a machine ID consistently:

Ack. Also DPM mode has LPAR UUID we should be using.
