Use RECEIVER_NOT_EXPORTED in CarrierPrivilegeAuthenticator.

Browse Source 
Passing one of RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED is
required for all code targeting T or above. The correct value
here is RECEIVER_NOT_EXPORTED because the receiver is being
registered in the system server and the broadcast comes from
the system server itself (same UID).

This does not need to be guarded by OS version because
CarrierPrivilegeAuthenticator is only used on T+.
