Mark VoicemailContract.VOICEMAIL_SMS_RECEIVED as protected broadcast

VOICEMAIL_SMS_RECEIVED is sent by the visual voicemail SMS filter in
telephony to the visual voicemail client. Marking the broadcast as
protected prevent non-system apps from faking this broadcast. Also
system apps can only send protected broadcast.
