Replaced github.com/docker/libcontainer with
github.com/opencontainers/runc/libcontaier.
Also I moved AppArmor profile generation to docker.
Main idea of this update is to fix mounting cgroups inside containers.
After updating docker on CI we can even remove dind.

Memory swappiness option takes 0-100, and helps to tune swappiness
behavior per container.
For example, When a lower value of swappiness is chosen
the container will see minimum major faults. When no value is
specified for memory-swappiness in docker UI, it is inherited from
parent cgroup. (generally 60 unless it is changed).

The cleanup to sysinfo package introduced a regression.
If memory cgroup isn't supported and --memory is specified when
starting a container, we should return info instead of nil in
checkCgroupMem(), otherwise we'll access a nil pointer.

If memory cgroup is mounted, memory limit is always supported,
no need to check if these files are exist.

Now that docker sets /proc/sys/net/ipv4/ip_forward by default (unless
the user manually specifies "-ip-forward=false"), there's no need to
warn if its disabled.
