Use "docker load" to create "scratch" in hack/make/test-integration-cli (instead of implicitly pulling it from the index)

tianon · tianon · commit c8381d672226 · 2014-04-28T22:26:25.000-06:00
Creating the "docker save" tarball for "scratch" is pretty simple.  I've also extrapolated the "docker build -t busybox ." logic into a separate "hack/make/.ensure-busybox" file so that it can eventually be reused easier.
