AudioService: catch RuntimeException for IServiceManager.getService

IServiceManager.getService() can throw a RuntimeException and
AudioService can handle that the same way it currently handles the
RemoteException from the same method.

Bug: 218588089
Test: Boot cuttlefish with a fake local ServiceManager with no hwservicemanager
installed.
