Title: Fix TestHostsLinkedContainerUpdate races

Also here I've introduced new binary in integration-cli container - `nsinit`.
One suspicious place is that I need to `go get github.com/codegangsta/cli` for compiling `nsinit`. I personally think that this is okay, because we use it only in `integration-cli`.
This test survived ~500 runs for me with this patch.
