Update kubernetes dependencies to 1.21.1

As part of this change, use the resizefs implementation from
`k8s.io/mount-utils`. This gets rid of the last reference to
`k8s.io/kubernetes`, so we no longer need to vendor it 🎉.

While we're here, tidy up the go.mod file a bit by putting all the `replace`s in
one stanza. I suspect we ended up with some separated out at the end via
previous runs of update-k8s.sh, but I don't see any good reason to keep it that
way.
