Support product specific VTS test configuration

The tuner vts will read the system property
ro.vendor.vts_tuner_configuration_variant as the suffix of the config
file to read. Vendor who wants to support multiple region for a single
SoC need to put all VTS config with different suffix as
/vendor/etc/tuner_vts_config_aidl_V1.{suffix}.xml on device.
