Subject: [PATCH] Make telephony actions unconditionally protected

The telephony broadcast actions are listened-to by the system server
but the telephony package isn't always present. This represents a
security issue where on a device without telephony any app can send
these broadcasts.

Due to b/161145287 it also currently means that devices without
telephony won't boot due to not specifying EXPORTED/NOT_EXPORTED. This
patch fixes that for telephony broadcasts.
