irmd, lib: use shm_du_map as lockfile.
Added the pid of the irmd to the shm_du_map. The IRMd will check for an existing shm_du_map. If there is an existing file, it will exit if the owner IRMd is running or remove it if the owner IRMd is not running. Also simplifies calculation of the shm_du_map pointers and corrects exiting calls for the IRMd. Fixes #8.
