clients: teach simple-dmabuf-v4l to deal with flipped input
The v4l2 API can be queried to detect if the input video image is
horizontally or vertically flipped. If the image is y-flipped, we can
set the ZWP_LINUX_BUFFER_PARAMS_V1_FLAGS_Y_INVERT flag to notify the
compositor. If the image is h-flipped, we can only print a warning
since linux_buffer_params_v1 does not support horizontal flipping.
