dvbsubenc: Forward GAP events as-is if we wouldn't produce an end packet and are not in the middle of an existing subtitle

Browse source 
An end packet is only produced once for the last subtitle, so multiple
GAP events between subtitles would result only in a single end packet
and nothing else otherwise. This would potentially starve downstream
then, so instead forward the GAP events in that case.
