Change conditional compilation logic for 'fork()' vs. 'vfork()'. fork() will now be the default on ALL platforms.

ToDo?  Add a new CMake variable to explicitly turn on vfork(), overriding the default?
       (seems undesirable / overkill (to me) but expect some push back)

Request review by Adam.  Especially interested IF the new default causes failures
on HPC (e.g. chama, redsky) systems.
