Streamline VM overlays and rootfs packages

Browse source 
Move the default guest package list into a repo manifest and record a hash beside built rootfs images so run/make-rootfs can warn when the docker-ready image is stale.

Switch the Firecracker launch path to a single sparse root overlay per VM instead of separate /home and /var disks, so many VMs can share the same base image while still installing packages under /var and working from /root.

Keep older images bootable by masking stale home.mount and var.mount units at boot, and scrub those obsolete fstab entries when customize.sh rebuilds an image. Verified with bash -n on the updated scripts; no live VM boot was run in this environment.
