Audio VTS: do not test duplicate policy configuration file

This patch only modifies the VTS tests.

O generic policy configuration fallback is incorrect
(see I2a39606cd820b5cd27a640248bf692204ec2cd71 for the fix).
Nevertheless, has no impact on products because this fallback
is only used in aosp builds and GSI.

Unfortunatly, this break the VTS test when run agains GSI.
Because it is too late to change GSI for Oc and DR,
relax the test to support current O GSI.

For P, ihis patch will not be part of VTS
and the fallback config will be fixed.
