‘union-build’ emits a warning, but it’s only visible in build logs.

Currently, ‘guix install’ errors out if you try to install two
same-named packages with a different version number or a different store
file name (typically via propagated inputs).
Here, ‘emacs’ and ‘emacs-xwidgets’ have different names, so it doesn’t
complain.
Perhaps we should offer a way to annotate packages as conflicting with
one another?
Thanks,
Ludo’.
