setup: show how to set the module policy for imports
This is not technically needed, since mercurial.__version__
does not exist as a native module, but, without this style wrappings,
if something else had a native flavor, the module loader would get
upset.
In principle, the `env` object is trying to set HGMODULEPOLICY for
children, so, conceptually we should set it for this in-process
child.
