Cygwin: console, pty: Stop ignoring Ctrl-C by IGNBRK.

Browse Source 
- Perhaps current code misunderstand meaning of the IGNBRK. As far
  as I investigated, IGNBRK is concerned with break signal in serial
  port but there is no evidence that it has effect to ignore Ctrl-C.
  This patch stops ignoring Ctrl-C by IGNBRK for non-cygwin apps.
