kconfig/[mn]conf: handle backspace (^H) key
[ Upstream commit 9c38f1f044080392603c497ecca4d7d09876ff99 ] Backspace is not working on some terminal emulators which do not send the key code defined by terminfo. Terminals either send '^H' (8) or '^?' (127). But currently only '^?' is handled. Let's also handle '^H' for those terminals.
