plm/alps: fix orted based launch failures.
Turns out that when one builds Open MPI with --disable-dlopen for Cray, a whole bunch of cray specific libraries get linked in to the orted executable. One of these is Cray PMI. The Cray PMI has a ctor which, if run, causes job launches using mpirun to fail. This commit suppresses the running of the ctor and thus prevents failure to launch.
