SamsungExynos3RIL: fix sim PIN handling

(cherry-picked from cm-10.2)

- fake sim status changed on incorrect PIN (rebase from RIL)
- notify PIN-correct using RADIO_ON instead of on signal strength
  (causes ICC to be queried all the time if no SIM is inserted)

SMSDispatcher: Fix determining the defaultSmsApp for proxied messages

We can't rely on the calling UID, since for re-broadcasted texts that'll
always be the telephony itself; so if called by the framework, use
the sentIntent creator to determine which app originated the message
