Silence warnings about bad .po files

Sadly, Transifex doesn't seem to acknowledge that the generated files
are bad.  Also, I don't want to introduce any infrastructure to
fix the files every time after I download them.
So they stay broken, and the warnings must be silenced.
Sadly, this means that future warnings will get ignored, too.
Let's hope this won't go too bad.
