[Mac] Force the Process Manager to start up when loading the symbols for process naming. The call seems to use those mach ports, and relying on some other code to start it up seems to be a crap shoot.

BUG=40583
TEST=release builds get the renderer, worker, etc. named as such in Activity Monitor.  Might also help the Null named processes.
