Subject: [PATCH] plugins: no sinkpad bufferpool when decoder

Right now, the decoders create a buffer pool for their sink pad which is not
used at all, because the decoders have never proposed it to upstream.

This patch avoids the buffer pool instantiating when the element inherits from
the GstVideoDecoder class.
