Don't bind host's /run in multipathd container

The multipathd daemon uses a hard-coded pidfile path that conflicts
with the one we use for conmon on the host. If we bind /run:/run
then multipathd overwrites the host file with its own pid, and this
interferes with systemd's ability to manage the service via the
pidfile. systemd expects the pidfile to contain the host's conmon
pid, not the multipathd daemon's pid.
