Initial support for installing to an empty disk device

Right now, this just installs a new GPT partition table on the disk, with the
partitions samizdat needs. Then nothing happens because nothing else is
implemented.

It will only allow a disk to be wiped like this if there are no partitions on
the disk (or if the only partitions on the disk are partially-installed samizdat
partitions).
