Vendor libkv @ 458977154600b9f23984d9f4b82e79570b5ae12b

Signed-off-by: John Howard <jhoward@microsoft.com>

This also adds go.etcd.io/bbolt as boltdb/bolt is no longer
maintained, and we need etcd-io/bbolt#122 which
was merged in https://github.com/etcd-io/bbolt/releases/tag/v1.3.1-etcd.8
in order to fix moby/libnetwork#1950.

Note that I can't entirely remove boltdb/bolt as it is still used by
other components. Still need to work my way through them.... These include
containerd/containerd (containerd/containerd#2634),
docker/swarmkit; moby/buildkit. And probably more....
