Cygwin: pty: Add a workaround for ^C handling.
- Pseudo console support introduced by commit
169d65a5774acc76ce3f3feeedcbae7405aa9b57 sometimes cause random
crash or freeze by pressing ^C while cygwin and non-cygwin
processes are executed simultaneously in the same pty. This
patch is a workaround for this issue.
