Fix for BC-123 - #420

The Lambda environment includes the function's AWS credentials (AWS_SECRET_ACCESS_KEY etc.), which student code could previously read via System.getenv. Deny RuntimePermission getenv.* to confined student code, and wrap the AWS SDK calls that run while student code is on the call stack (output adapter, input adapter, content manager) in AccessController.doPrivileged, since the SDK re-reads its credentials from the environment on every request.
