Audio VTS: Test now use Android.mk

To validate the audio_policy_configuration.xml against a schema,
libxml2 is used.
Unfortunately, libxml2 uses Android.mk in oc-dev thus can not be used
from the tests which uses Android.bp.

It has been deemed safer to transform the tests to use Android.mk rather
than backporting the Android.bp patch from master.

Test: Compile
