Add FrameworksVibratorServicesTests to android/os test mapping

Add file-pattern presubmit test mapping for changes in vibrator-related
sources from android.os.* and android.os.vibrator.*.

This ensures that any changes in these source folders will also trigger
FrameworksVibratorServicesTests, which relies on VibrationEffect and
other client classes.
