LineageParts: Stats: Try getting a valid country code

* As per https://developer.android.com/reference/android/telephony/TelephonyManager#getNetworkCountryIso()
  we are either getting a valid lowercase 2 character alpha-2 country
  code or an empty string. Make it uppercase so the server needs to do
  less work on those strings
* Additionally the doc states to be unreliable on CDMA networks, so in
  those case don't use the result
* To get a country code anyway, use getCountry() on the current locale
  - we will get either an uppercase 2-letter or a 3-digit code,
  which we only use when it's the 2-letter result
