selftests: drivers/s390x: Add uvdevice tests



Adds some selftests to test ioctl error paths of the uv-uapi.
The Kconfig S390_UV_UAPI must be selected and the Ultravisor facility
must be available. The test can be executed by non-root, however, the
uvdevice special file /dev/uv must be accessible for reading and
writing which may imply root privileges.

  ./test-uv-device
  TAP version 13

  # Starting 6 tests from 3 test cases.
  #  RUN           uvio_fixture.att.fault_ioctl_arg ...
