Use relaxed default constructor configuration in Arquillian Weld embedded adapter for SE environment

Weld exposes a relaxed default constructor configuration that enables to relax the constraint of having to declare a default constructor for proxied bean types.

This configuration is very useful in a number of use cases, notably when integrating with third-parties libraries that do some heavy initialisation in their default constructors, like Apache Camel.

This is enabled by default in Weld SE so it would be consistent to enable that mode as well when using the corresponding Arquillian adapter for the SE environment.
