Cygwin: pty: Fix the behaviour of Ctrl-C in the pseudo console mode.

Browse Source 
- When the I/O pipe is switched to the pseudo console side, the
  behaviour of Ctrl-C was unstable. This rarely happens, however,
  for example, shell sometimes crashes by Ctrl-C in that situation.
  Furthermore, Ctrl-C was ignored if output of non-cygwin program
  is redirected to pipe. This patch fixes these issues.
