We can run these tests on the pSeries machines too,
we were just missing to properly parse the machine names.

Note: we have to exclude the versioned machines from QEMU 2.8
to 2.11 which fail, such:

  TestFail: machine type pseries-2.8: No Transactional Memory support in TCG, try appending -machine cap-htm=off
