Firecracker: Make root disk configurable
Add a FCROOTFSSZ variable which defaults to "1g" which controls the
size of the Firecracker root filesystem; it can be set as low as "300m"
at present.
Allow WITHOUTS to be overridden if users want to build a root disk with
more -- or fewer -- parts of the FreeBSD base system.
