Now `dockerd-rootless.sh` launches RootlessKit with `--detach-netns`
so as to run the daemon in the host network namespace.
The libnetwork namespaces are allocated inside the "detached" netns
(`$ROOTLESSKIT_STATE_DIR/netns`) that is associated with slirp4netns,
vpnkit, pasta, etc., as the rootless daemon has no `CAP_NET_ADMIN` for
the host network namespace.
This will enable:
- Accelerated (and deflaked) `docker pull`, `docker push`, `docker build`, etc
- Proper support for `docker pull 127.0.0.1:.../...`
- Proper support for `dockern run --net=host`

The daemon started by the test-integration script needs to run without
firewalld integration to make sure that daemons started by networking
tests will handle firewalld reload without any interference (i.e.
without another daemon racing against them to recreate the iptables
chains).
Most tests are already running their own daemons, but the few that don't
and need firewalld integration are updated to start their own.

This package is used internally by the daemon, and was only used out
side of the daemon by pkg/plugins (for which we still need to look
where it should be kept).
Making it internal because it's trivial to implement if needed by
anyone. The only reason it's a package is to keep it central, and
to make it easier to discover where we have rootlesskit-specific
codepaths in our codebase.
