Set default value for the fixed delay to 0
This CL reverts part of commit aa5a43fce8 because we found out
that:
- The non-tuned APM use case doesn't pick default values from
aec_config.h but from source code.
- The tuned APM use cases are all explicitly setting the
'fixed_capture_delay_samples' value in their own aec.ini
Therefore in this change we set fixed_capture_delay_samples back
to its default value in echo_canceller3_config.h
Moving forward we want 'fixed_capture_delay_samples' to be zero
whenever system software loopback is used. For hardwre loopback
case, aec.ini should provide a tuned compensate value.
