Setup TelephonyPermissions mocks for all SubscriptionController tests

The WRITE_SMS appop check in TelephonyPermission's phone number access
verification has been moved after the READ_PHONE_STATE and carrier
privilege check. Due to the new phone number access requirements for
target R+ any tests that query for SubscriptionInfo objects must setup
the mocks for the TelephonyPermission checks; this commit does this in
the setUp method as a majority of the SubscriptionController tests will
perform this query.
