Now, we don't require it to be the current locale:

The systemd package ensures to pass LANG/LC_ALL pointing to an UTF-8
locale.

So even if your current locale is something else, as long as
en_US.UTF-8 is *available*, things are going to work.

That being said, I also dislike this solution, and think the sytemd
build system should be fixed instead.
