basesink: Don't drop buffers

So as brought up by Tim, a completly valid scenario would be existing code the
do:

Take a snapshot:
  uridecodebin ! video/x-raw ! appsink

If it picks a file containing raw video directly, and a demuxer that don't try
to clip on accurate seek (take TS), the resulting snapshot would be wrong if we
don't do any clipping.
