Modify the code path of the ifdef NOTYET part of _kse_single_thread():

o  Don't reinitialise the atfork() handler list in the child.  We
   are meant to call the child handler, and on subsequent fork()s
   should call all three functions as normal.
o  Don't reinitialise the thread specific keyed data in the
   child after a fork.  Applications may require this for context.
o  Reinitialise curthread->tlflags after removing ourselves from
   (and reinitialising) the various internal thread lists.
o  Reinitialise __malloc_lock in the child after fork() (to balance
   our explicitly taking the lock prior to the fork()).

With these changes, it is possible to enable the NOTYET code in
thr_kern.c to allow the use of non-async-safe functions after
fork()ing from a threaded program.

[_malloc_lock reinitialisation has since been moved to avoid polluting the
!NOTYET code]
