When slirp4netns v0.4.0+ is used, now slirp4netns is hardened using
mount namespace ("sandbox") and seccomp to mitigate potential
vulnerabilities.

lxc-user-nic can eliminate slirp overhead but needs /etc/lxc/lxc-usernet to be configured for the current user.
To use lxc-user-nic, $DOCKERD_ROOTLESS_ROOTLESSKIT_NET=lxc-user-nic also needs to be set.
This commit also bumps up RootlessKit from v0.3.0 to v0.4.0:

- docker/libnetwork#2368 (windows) Pick a random host port if the user does not specify a host port
Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
Now `docker run -p` ports can be exposed to the host namespace automatically when `dockerd-rootless.sh` is launched with
`--userland-proxy --userland-proxy-path $(which rootlesskit-docker-proxy)`.
This is akin to how Docker for Mac/Win works with `--userland-proxy-path=/path/to/vpnkit-expose-port`.
The port number on the host namespace needs to be set to >= 1024.
SCTP ports are currently unsupported.

Please refer to `docs/rootless.md`.
TLDR:
* Make sure `/etc/subuid` and `/etc/subgid` contain the entry for you
* `dockerd-rootless.sh --experimental`
* `docker -H unix://$XDG_RUNTIME_DIR/docker.sock run ...`

Update to the latest patch release of 17.06.2. This
keeps the same API requirements.
This also enables pre-built binaries for armhf instead
of compiling from source.

These scripts explicitly use Bash, so we should be able to use
`[[` instead of `[` (which seems to be recommended).
Also added curly brackets to some bare variables, and quoted some paths.
This makes my IDE a bit more silent :-)
