Configbuilder: _detect_module_system() and _get_container_systems() don't work as expected.

Description of the bug

The _detect_module_system method in hpccustomisation.py should run module --version and return True if the command finished successfully and False otherwise. This should result in unhiding the module_system input field.

A similar method is defined in finalinfradetails.py and is used within the _get_container_systems() method, which also isn't working as expected, which should be detecting the container software on the system and auto-filling the container_system input field.
