opensles: call setCallerName() for MediaMetrics

This can be used to tell whether OpenSL ES
created the AudioTrack or AudioRecord object.

Bug: 149850236
Test: adb shell dumpsys media.metrics --clear
Test: Run an app that uses OpenSL ES.
Test: adb shell dumpsys media.metrics
Test: Look for "callerName=opensles" in the dump.
