Cygwin: ctty: Remove old 'kludge' code. 

Remove old 'kludge' code which does not seem necessary anymore. The
comment of the 'kludge' is as follows.

  * syscalls.cc (setsid): On second thought, in the spirit of keeping
    things kludgy, set ctty to -2 here as a special flag, and...
    (open): ...only eschew setting O_NOCTTY when that case is detected.
