[PATCH 6/6] tests/acceptance/virtio_seg_max_adjust: Restrict to Linux host

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

This test is failing on OSX:

  TestFail: machine type pc-i440fx-2.0: <class 'TypeError'>

Looking at the job.log:

  Unexpected error in object_property_find() at qom/object.c:1201:
  qemu-system-x86_64: -device virtio-blk-pci,id=scsi0,drive=drive0: can't apply global virtio-blk-device.scsi=true: Property '.scsi' not found

Which makes sense looking at hw/block/virtio-blk.c:

  1261 static Property virtio_blk_properties[] = {
  1262     DEFINE_BLOCK_PROPERTIES(VirtIOBlock, conf.conf),
  ...
  1268 #ifdef __linux__
  1269     DEFINE_PROP_BIT64("scsi", VirtIOBlock, host_features,
  1270                       VIRTIO_BLK_F_SCSI, false),
  1271 #endif

Fix by only running this test on a Linux host:

 (38/55) tests/acceptance/virtio_seg_max_adjust.py:VirtioMaxSegSettingsCheck.test_machine_types:  SKIP: Host OS is not Linux
