python-blivet: Fix path and call to wipefs.

First of all, the path to wipefs didn't work at all, and though it is
documented, the "-f" flag only works when used as a long option ("--force").
This is probably fixed upstream in util-linux, but using the long-option will
stay compatible.

python-nevow: Fix indentation of expression.

No functionality change, the expression just got a bit too far to the right :-)

python-blivet: Patch in paths for mount and lsof.

This adds the correct store paths for mount, umount and lsof to blivet as these
commands are still generic enough to _not_ add them as a dependency.

python-blivet: Fix pvscan to not require lvmetad.

The --cache argument to pvscan won't work on NixOS, for specifics about this,
please have a look at:

radeon-juniper: Update to new JUNIPER_rlc.bin.

Kinda icky to not have archives available here, but I got an error during VM
tests because of an sha256sum mismatch, hence the update. Maybe Hydra has cached
this?

And yes, I checked twice, it wasn't a broken download - there really *is* a new
upstream version available.

python-packages: Add nixpart version 0.1.

This version is preliminary because it quite heavily depends on pykickstart
(through blivet) and the roadmap is to have a nice NixOS attrset-based
specification of partitions.

Currently the main purpose for this is in preparation for the Hetzner nixops
backend, but we might want to make this part of the standard NixOS installer.
