flatten dataset structure and persist more

Modified options used in disk creation so that consumers of this
module will actually pass disko virtual machine tests.

The flat dataset structure is changed from the xnet disk module,
mainly since I never really made use of the nesting properly. The only
place nesting matters is really in the persist dataset, and that one
is managed by hand anyway.

Although the changes pass tests and seem fine, they have not been
tested on actual hardware yet since the dataset layout changes are
destructive to any running machines, and cannot be simply reverted,
since they alter the disk.

/var, /root, and extras are now persisted since they do not expect to
be wiped on reboot. I never really had problems with this but would
rather minimize messing with SystemD's expectations regarding /var especially.
