console: Support delete as well as backspace
Some terminals do not generate backspace correctly, so accept delete
as a substitute.
BUG=chrome-os-partner:10147
TEST=manual:
ssh into workstation, then telnet to serial port (with ser2net running)
See that the backspace key now works correctly, instead of injecting
strange characters into the terminal.
