This commit moves the backing files to /dev/shm to avoid limitations that may be set on /tmp. The files are registered with pmix to ensure they are cleaned up after an erroneous exit.

Since open-mpi/ompi@47fd231 the backing file is now in /dev/shm by default. As a consequence, the backing file name has to include the jobid so more than one job can run at a time.
