[Buildroot] [PATCH] support/kconfig: fix 'space' to (de)select options

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

In case a menu has comment without letters/numbers (eg. characters
matching the regexp '^[^[:alpha:][:digit:]]+$', for example - or *),
hitting space will cycle through those comments, rather than
selecting/deselecting the currently-highlighted option.

This is the behaviour of hitting any letter/digit: jump to the next
option which prompt starts with that letter. The only letters that
do not behave as such are 'y' 'm' and 'n'. Prompts that start with
one of those three letters are instead matched on the first letter
that is not 'y', 'm' or 'n'.

Fix that by treating 'space' as we treat y/m/n, ie. as an action key,
not as shortcut to jump to  prompt.
