Block USSD requests via TelephonyManager when carrier does not allow it.

Some carriers have expressed concern of the new USSD APIs in
TelephonyManager.  Adding the ability to block the execution of USSD
codes using the new APIs via TelephonyManager on a per-carrier basis.
The USSD code will result in the "failed" callback via the API.
