We need this before copying the initial environment as that environment gets restored before loading the module (which is exactly where we want to target a conditional load)

@ocaisa Let's move this up, as the very first thing we do in __init__, just to make sure that we never do anything that involves calling out to external tools (which could take this into account) before this is set.

Actually, this should be done way earlier, in main.py ?

The use case for this is
buildenvin EESSI (https://gitlab.com/eessi/support/-/issues/213), where you might want to auto-load abuildenvwith your compiler, but not if you are in an EasyBuild session.
