Whitelist READ_PRIVILEGED_PHONE_STATE for the contacts provider

In Android 10 access to device identifiers was moved from a runtime
permission to the privileged READ_PRIVILEGED_PHONE_STATE permission.
One of the non-resettable identifiers missed was SubscriptionInfo#
getIccId. The contacts provider currently uses this ID to upgrade
to version 1003 of the database; to ensure there are no issues with
this upgrade this permission is being whitelisted for the contacts
provider.
