In order to properly run tests, we need to fix the unicode tests and
after some search, I have found that Ludo (who is also the <nixpkgs>
maintainer of parted) already reported this upstream and also provided a
solution:
http://lists.gnu.org/archive/html/bug-parted/2014-08/msg00003.html
I'm updating parted to 3.2, because the latest blivet implementation
relies on it for device geometry calculations.
