Fix: Don't (incorrectly) rewrite C into default stop action

Rewriting the ^C into a default stop action causes docker to run the default stop action.
It will run whatever is specified by STOPSIGNAL, or SIGTERM by default.

This change allows wings to received the full data and issue the correct signal.
