Add fallback for datasource without UPDATE_APP_OP_STATS

If the datasource is not in a trusted platform component then in would not
have UPDATE_APP_OPS_STATS. The problem is that an app is exposing runtime
permission protected data but cannot blame others in a trusted way which
would not properly show in permission usage UIs. As a fallback we are
adding a proxy op handling blaming the datasource and the caller.
