tests/acceptance/virtio_check_params: Disable the test

This test fails on various CI:

- Using QEMU 4.0:
  tests/acceptance/x86_cpu_model_versions.py:X86CPUModelAliases.test_none_alias:  ERROR: 'alias-of' (0.45 s)

- On OSX
  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

- When removing unavailable machine:
  VirtioMaxSegSettingsCheck.test_machine_types: ERROR: list.remove(x): x not in list (0.12 s)

- Using Xen:
  xencall: error: Could not obtain handle on privileged command interface: No such file or directory
  xen be core: xen be core: can't open xen interface

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

- On S390X configured with --without-default-devices:
  ERROR: qemu-system-s390x: -device virtio-scsi-pci,id=scsi0: 'virtio-scsi-pci' is not a valid device model name

Disable it for now.
