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.
