avcodec/libvpx: fix assembling vp9 packets with alpha channel

There's no warranty that vpx_codec_encode() will generate a list with the same
amount of packets for both the yuv planes encoder and the alpha plane encoder,
so queueing packets based on what the main encoder returns will fail when the
amount of packets in both lists differ.
Queue all data packets for every vpx_codec_encode() call from both encoders
before attempting to assemble output AVPackets out of them.

Fixes ticket #9884
