Fix SecurityException at getActiveSubscriptionInfoList() on N and O

Creating ConnectivityUtil instances after checking the minimum set of
permissions since SubscriptionManager#getActiveSubscriptionInfoList()
requires READ_PHONE_STATE and users can revoke the permission.
On P and beyond, the subscription list will be filtered instead when no
permission.
