nixpart: Update to latest master version

This is mainly for testing purposes during the WIP branch, but it should
actually do partitioning for some of the NixOS VM tests (particularily
the .btrfs test).

I've tagged this specifically as unstable-1.0.0 to make sure noone is
seriously going to use it yet (except for playing around of course).
