audio: update audio_policy_volumes.xml

Update below stream's volume curves to refine system sound output
from speaker too loud in the lowest volume.

  <volume stream="AUDIO_STREAM_SYSTEM" deviceCategory="DEVICE_CATEGORY_SPEAKER">
  <volume stream="AUDIO_STREAM_RING" deviceCategory="DEVICE_CATEGORY_SPEAKER">
  <volume stream="AUDIO_STREAM_ALARM" deviceCategory="DEVICE_CATEGORY_SPEAKER">
  <volume stream="AUDIO_STREAM_NOTIFICATION" deviceCategory="DEVICE_CATEGORY_SPEAKER">
  <volume stream="AUDIO_STREAM_DTMF" deviceCategory="DEVICE_CATEGORY_SPEAKER">

Refine audio-tables.mk location to make sure the xml is updated.
