Since rootlesskit removed vendor folder, building it has to rely on go mod.
Dockerfile in docker-ce-packaging uses GOPROXY=direct, which makes "go mod"
commands use git to fetch modules. "go mod" in Go versions before 1.14.1 are
incompatible with older git versions, including the version of git that ships
with CentOS/RHEL 7 (which have git 1.8), see golang/go#38373
This patch switches rootlesskit install script to set GOPROXY to
https://proxy.golang.org so that git is not required for downloading modules.
Once all our code has upgraded to Go 1.14+, this workaround should be
removed.

Requires cgroup v2 host with crun.
Tested with Ubuntu 19.10 (kernel 5.3, systemd 242), crun v0.12.1.

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:

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 ...`
