The test to test that a forked child process can do VIDIOC_STREAMOFF
without being blocked does not kill the child in the event of a failure
(ie. the child process blocks on VIDIOC_STREAMOFF). This causes the
video device node to still be in use even after v4l2-compliance
completes execution. Kill the child process after this test fails.
