modules/audio_processing: Updates output_data_fixed.pb test file

In r6591 a shift macro was removed affecting AECM. In addition to that change a bug was fixed. The fix added a few voice_counts in ApmTest.Process.

This CL updates the reference file, even though it is not used in practice since the test is currently turned off for Android (where AECM is used).
