The SetupTestOSContext calls were made conditional in
https://github.com/moby/libnetwork/pull/148 to work around limitations
in runtime.LockOSThread() which existed before Go 1.10. This workaround
is no longer necessary now that runtime.UnlockOSThread() needs to be
called an equal number of times before the goroutine is unlocked from
the OS thread.
Unfortunately some tests break when SetupTestOSContext is not skipped.
(Evidently this code path has not been exercised in a long time.) A
newly-created network namespace is very barebones: it contains a
loopback interface in the down state and little else. Even pinging
localhost does not work inside of a brand new namespace. Set the
loopback interface to up during namespace setup so that tests which
need to use the loopback interface can do so.

The io/ioutil package has been deprecated in Go 1.16. This commit
replaces the existing io/ioutil functions with their new definitions in
io and os packages.

After moving libnetwork to this repo, we need to update all the import
paths for libnetwork to point to docker/docker/libnetwork instead of
docker/libnetwork.
This change implements that.
