Test that V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS is reported equally for
both MMAP and DMABUF memory types. If supported, try to orphan buffers
by calling reqbufs(0) before unmapping or closing DMABUF fds.
Also close exported DMABUF fds and free buffers in testDmaBuf if
orphaned buffers are not supported.
