Subject: [PATCH] videoaggregator: push the caps event as soon as we receive it

Along with the required mandatory dependent events.

Some elements need to perform an allocation query inside
::negotiated_caps().  Without the caps event being sent prior,
downstream elements will be unable to answer and will return
an error.
