Fix decoder is queued buffer with timestamp TIME_END_OF_SOURCE

Browse Source 
ExoPlayer queues the EOS buffer to the decoder with offset/size/timestamp all
equal to zero, and a EOS flag.

69769c77b3 set TIME_END_OF_SOURCE on the EOS buffer from the extractor.
Queueing the EOS buffer to the decoder with TIME_END_OF_SOURCE causes some
decoders to output wrong timestamps in its output.

This CL replicates what ExoPlayer does in Transformer.
