Use locale to decide out-of-service message

Instead of using the resource with mcc/mnc overlay (which doesn't work
when no SIM is inserted), we use LocaleTracker and a new resource which
is a list of the countries where the out-of-service message is
no-service. (e.g. Germany does not allow emergency calls without a SIM).
