primary-hal: Add separate manifest for android.hardware.audio interface.

Add new manifest for android.hardware.audio for anorak.
This is needed to avoid HIDL version conflict which was defined in
a project common to both QSSI 12 and QSSI 14 based anorak PL.
QSSI 14 based variant uses audio-android-hal.lnx.3.0.c2, hence
keep HIDL version 7.1 here.
Changes in Android.mk to pick this manifest fragment for anorak.
