baseparse: Don't add calculated bitrates until threshold

Browse source 
Waiting before posting calculated bitrates seems to be the
intent of the code, so avoid adding them to the tag list
pushed with the first frame.

When the threshold is reached, gst_base_parse_update_bitrates
sets tags_changed, so this posts the calculated ones right
that moment.

This prevents an insane average calculated from just the
first (key) frame from getting posted.
