Provide an MCA param to control hwloc shmem sharing

There are times when it can be beneficial to separate
the hwloc topology memory images between PRRTE and
applications it might be running. Provide an MCA param
to indicate that the topology should not be shared via
shmem. Default it to true (i.e., the topology shall be
shared in memory).

(cherry picked from commit 413ff22)

Update the directive list in check_multi

When checking for multiple directives, need to use
the "rtos" directive instead of "runtime-options".
Change to using the definitions for the directives
to ensure this follows along.
