ttydefchars ion ChromOS Linux is wildly useless

The wrong characters in the wrong order.  I have no idea why they
even have the thing defined, but we'll just stop using it since
it seems BSD systems are the only ones where it's useful...
instead just set V* to C* except ERASE and ERASE2 which we set both
to CTRL-H
