Telephony: Decode Virgin Mobile US MMS

Fixes receiving MMS as one or more sms from a 9999999999 number full of
gibberish.

Back in the CM7 days, a developer named Blarf (Blarfiejandro) started a
repo called Inferior Human Organs for the optimus S/V (LG LS670 and
VM670) when no-one could figure out how to get Virgin Mobile MMS working
in CM.

His MMS patch to decode Virgin's weird system for MMS was eventually
absorbed by CM10.2 by  rukin5197. Without it, MMS comes in as one or
more sms from a 9999999999 number full of gibberish.

bigsupersquid took the CM10.2 patch for this fix and updated it enough
to work in CM11. However because he doesn't have Gerrit, he asked others
to integrate the fix for him.
