Deinterlace: in query_caps return only supported formats if filter is interlaced

Browse Source 
In some cases the currently set GstVideoInfo is not interlaced, but
upstream caps are interlaced and the info is passed in the filter,
we should take that info into account and make sure that we do not
consider that case as a "pass through" case.
