HTCTegra3RIL: Add custom RIL for correct STK handling (1/2)


Change-Id: Ia12c85f43b5be0fe4e1cd3c3511490fd5cebe3af
GsmSST: Disregard any invalid verbose values for timezones in NITZ requests

And assume anything resulting in "GMT" is invalid, since that's the
default value returned by libcore

Should fix CYAN-2271
