Always mount a /run tmpfs in the container

All modern distros set up /run to be a tmpfs, see for instance:
https://wiki.debian.org/ReleaseGoals/RunDirectory

Its a very useful place to store pid-files, sockets and other things
that only live at runtime and that should not be stored in the image.

This is also useful when running systemd inside a container, as it
will try to mount /run if not already mounted, which will fail for
non-privileged container.
