Cygwin: pty: Fix a possible race issue in initialization of pcon.

- Currently, tty::pcon_start flag is cleared before transfer_input()
  in master::write(), however, the code in setup_pseudoconsole()
  waits for transfer_input() using tty::pcon_start. This possibly
  causes the race issue. The patch fixes this potential issue.
