 score: Improve scheduler helping protocol

 Only register ask for help requests in the scheduler unblock and yield
 operations.  The actual ask for help operation is carried out during
 _Thread_Do_dispatch() on a processor related to the thread.  This yields
 a better separation of scheduler instances.  A thread of one scheduler
 instance should not be forced to carry out too much work for threads on
 other scheduler instances.

 Update #2556.
