BUG=XWALK-2362
This  function is totally same as `system_info_cellular_network_mobile.cc`, please DONOT copy code. Instead of considering how to re-use code. In this case, add new file `system_info_cellular_network.cc` and move code there.

Same the initlization of `std::string SysInfoCellularNetwork::name_`
