Add support for sharing /dev/shm/ and /dev/mqueue between containers

This changeset creates /dev/shm and /dev/mqueue mounts for each container under
/var/lib/containers/<id>/ and bind mounts them into the container. When --ipc:container<id/name>
is used, then the /dev/shm and /dev/mqueue of the ipc container are used instead of creating
new ones for the container.
