Subject: [PATCH] EX-5260 pumount: test pumount with MDT0000 unmounted

Add tests (40a-40c, 41a) to verify that pumount can unmount a client
mount point with MDT0000 and OST0000 unmounted. Add a test (34a) that
pumount does not kill processes who are minding their own business on
other Lustre client mount points.
