Fix minor corner cases in BufferHubQueueProducer

1/ Set reasonable return value BufferHubQueueProducer::query.
2/ Don't error out for setSharedBufferMode(false),
setAutoRefresh(false), as they are just setting default values again.
3/ Supports addition buffer metadata: transformt, crop,
data_format (a.k.a. color_format).
4/ This also changes BufferHubQueueProducer to be based of
BnInterface<IGraphicBufferProducer> so that itself can be passed via Binder.
