Cygwin: pty: Revise the code which prevents undesired window title.

Browse Source 
- In current pty, the window title can not be set from non-cygwin
  program due to the code which prevents overwriting the window
  title to "cygwin-console-helper.exe" in fhandler_pty_master::pty_
  master_fwd_thread(). This patch fixes the issue.
