[MTS-MTQ] QuectelRadio implementation

Changed implementation of the QuectelRadio::getService

- Replaced sscanf with functions from MTS::Text
- Emulated the behaviour of TelitRadio::getService - return FAILURE
  when <Act> is not available

The TelitRadio::getService returns FAILURE when device stays without
a SIM card (probably, until it will be registered to the network)
