msm8953-common: sepolicy: Add missing rules for persist_audio_file

Browse Source 
* Rules for persist_audio_file have been removed for legacy devices.

* Instead of labeling "/mnt/vendor/persist/audio", which is the default
  path for audio calibration, label "/mnt/vendor/persist/factory/audio"
  as this is where Moto devices store these calibration files anyway.
