Cygwin: pty: Set input_available_event only for cygwin pipe.
- cat exits immediately in the following senario.
1) Execute env CYGWIN=disable_pcon script
2) Execute cmd.exe
3) Execute cat in cmd.exe.
This is caused by setting input_available_event for the pipe for
non-cygwin app. This patch fixes the issue.
