AudioFlinger: Add memory leak checking for HAL
$ adb shell setprop libc.debug.malloc.program android.hardware.audio.service
$ adb shell setprop libc.debug.malloc.options backtrace=8
$ adb shell setenforce 0
$ adb shell pkill audioserver
$ adb shell dumpsys media.audio_flinger
Test: Check the audio flinger dumpsys as above.
