A2DP: AAC encoding counter errata

When the encoder interval is 23 milliseconds per tick for {44.1 kHz /
16 bits per sample / Stereo}, 3 microseconds shift every tick would
cause one AAC frame mismatched after 180 seconds. Here try to adjust the
timeline to increase the accuracy by following methods:

1. add the remainder back to the timeline when converting the time
   period to data size.
2. change the timestamp to be presented by values in 1/10 microseconds.
