patch for the seek example

If queue2 is buffering to disk and if a seek is performed after the latest
buffered position queue2 fails to forward the seek event upstream so it can be
handled by the src element.

The perform_seek_to_offset is not called at all. What I can observe with the
seek example (patched, see attached file) is that if i seek 1 minute after the
current playback position the video pauses while queue2 downloads the missing
data. Playback is resumed when queue2 has buffered enough.

I think that perform_seek_to_offset is not called because find_range() always
returns the initial range that was created.

To test (from -base):

./tests/examples/seek/seek 16
