broadcastradio@2.0 VTS uses FM frequency invalid in some regions

In Japan FM frequency range is 76-95MHz thus FmTune test using
hardcoded 101.1MHz fails on devices preconfigured for this
region when TunerSession::tune returns INVALID_PARAMETER.
Proposed new frequency is valid in all regions.

Test: run VtsHalBroadcastradioV2_0TargetTest on hardware units
configured for Europe, US, Japan (and preferably other) analog
tuner regions

Bug: b/177916339
