Cygwin: pty: Additional fix for transferring input at exit. 

The commit 3456e8b7db does not fix transferring input at exit
appropriately. If the more than one non-cygwin apps are executed
simultaneously and one of them is terminated, the pty master failed
to send input to the other non-cygwin apps. This patch fixes that.

Fixes: 3456e8b7db ("Cygwin: pty: Fix transferring type-ahead input between input pipes.")
