avcodec/libwebpenc_animencoder: stop propagating bogus empty packets

Browse Source 
Packets must have at least one of data or side_data. If none are available,
then got_packet must not be signaled.

The generic encode code already discarded these empty packets, but it's better
just not propagating them at all.
