support/kconfig: ppply upstream nconfig ncurses/ncursesw fix

Browse Source 
Buildroot's "make nconfig" command stopped working a while ago on
Gentoo systems. Running the command would result in a crash.

The issue is caused by lxdialog's cflags which are also used to build
nconfig; It would detect *ncursesw* and turn on WIDECHAR support --
but the Makefile would still link to plain *ncurses* while building
nconfig (which was built without WIDECHAR support).

This would cause a crash after using *wattrset* on a WINDOW instance.
WIDECHAR *wattrset* would try to set the _color member in the WINDOW
struct which does not exist in the NON-WIDECHAR ncurses instance. It
would end up clobbering data outside the struct (usually _line entries).

An upstream patch fixes the issue, so we're applying it to Buildroot's
kconfig.

Subject: kconfig: nconfig: fix multi-byte UTF handling
Currently, Kconfig descriptions that use multi-byte UTF-8 characters
(such as MTD_NAND_CAFE) will have their menu entries dropped from the
'make nconfig' ncurses menu, and all subsequent entries in the same
window will be omitted. This seems to be due to the ncurses 'menu'
library, which does not traditionally handle UTF-8 >8-bit characters
properly.
The ncursesw library ('w' is for "wide") is written to handle these
UTF-8 characters, and is practically a drop-in replacement at the source
level. Use it by default, if available.
