Executing on a supervisor via a bolt/etc we must set up the embedded env properly

The main() function isn't going to be executed when the topology is sent over
to the cluster, redstorm/environment will be loaded properly on
supervisor-based execution however, so mucking with these globals there seems
like a reasonable approach
