dtrace: move psinfo to its own header file

The psinfo structure definition and related function prototypes have been moved
to their own header file to avoiding including dtrace_os.h in sched.h.  This is
also one step closer to providing the psinfo as a more generic piece of info,
rather than it being dtrace specific.
