Merge pull request #171834 (charm update)

I was approached by @muesli and the nixpkgs maintainer @penguwin about
it and given that basic ofborg checks are successful plus thei're the
upstream authors and the change in nixpkgs is minor I hereby decrided to
merge it despite being not involved in this nor being an expert about
the software in question.
