lchat: clean up terminal preparation
- reuse the value of `origin_term' instead of calling tcgetattr(3) twice
- change the following termios flags:
IMAXBEL - is an extension and does not provide much "real" value
OPOST - is mostly IB and thus not very useful
ECHONL - only has an effect if ICANON is set, which isn't the case for us
