bug#21859: 25.0.50; uesless binding for C-M-p in inferior-python-mode

I started emacs with -Q

Typed M-x run-python RET
Typed C-h f C-M-p
Saw ``C-M-p runs the command compilation-previous-error''
I had expected to see ``C-M-p runs the command backward-list'', or
perhaps backward-sexp.

Further, doing M-x local-set-key RET C-M-p backward-list RET has no
effect: it's still bound to compilation-previous-error.

(I'm going through old bug reports that have unfortunately not gotten
any responses.)

This is a binding from the `compilation-shell-minor-mode-map' keymap.
If you don't want that, you could probably switch that minor mode off in
these buffers.

That's also because of the minor mode map that has precedence over the
current major-mode map.
