Revert "video: Fix non-default usage of gst_video_sink_center_rect"

This reverts commit 899461d722e45f591eeddf33c405677170d63de4.

There seems to be a lot of code out there that does not properly initialize
the rectangles and then causes undefined behaviour. Including our video sinks.

Let's keep this out of 1.4, fix everything everywhere and keep it in 1.6
