bindings: make <Alt+Backspace> delete a word backwards, like in Bash 

It jars a bit that it is <Ctrl+Delete> that deletes a word rightward
and <Alt+Backspace> that deletes a word leftward.  But it's good to
also have a two-key keystroke bound by default to 'chopwordleft',
and not just the three-key <Ctrl+Shift+Delete>.

This fulfills https://savannah.gnu.org/bugs/?58709.
