The daemon was modified to tell RootlessKit about host port
mappings directly, rather than by running rootlesskit-docker-proxy
to make those updates.
DNAT rules created in rootless mode referred to the host IP address,
rather than the address seen as host address in the rootless network
namespace.
With these changes, port mappings work in rootless mode when
--userland-proxy=false - so, don't gate the RootlessKit API calls
on starting docker-proxy.

In preparation for the daemon passing a listen fd, add command line
option -use-listen-fd to indicate that the fd is present (as fd 4).
If the new flag isn't given, open the listener as normal.
Refactor the TCP and UDP proxies to be constructed with an existing
TCPListener or UDPConn, respectively. Lift the responsibilty of opening
the listener to the entrypoint. Per the Single Responsibility Principle,
this structure affords changing how the listener is created without
having to touch the proxy implementations.

Perhaps the testutils package in the past had an `init()` function to set up
specific things, but it no longer has. so these imports were doing nothing.

Since this command is part of the official distribution and even
required for tests, let's move this up to the main cmd's.
