These are all included in tier-x or tier-0 already.
Though it does drop bsdtar. This isn't really well-known enough to
belong here. It's included in FCOS because we use it in our scripts,
but it's not a requirement for any tier-1 logic AFAIK and I would be
surprised if users expected it there.
I don't entirely remember what happened here when forking from
CoreOS, but we definitely want toolbox and lsof at least, just
looking at the differences.
While we're here I did readd sos, but in another section.
