process: inspect error in case of a fatal exception

This makes sure that errors that shut down the application are
inspected with `util.inspect()`. That makes sure that all extra
properties on the error will be visible and also that the stack trace
is highlighted (Node.js internal frames will be grey and node modules
are underlined).
