avcodec/aptxenc: Process data in complete blocks of four samples only 

Do this by setting AVCodecInternal.pad_samples.
This prevents reading into the frame's padding and writing
into the packet's padding.

This actually happened in our FATE tests (where the number of samples
is 2 mod 4), which therefore needed to be updated.
