kconfig/nconf: Initialize the default locale at startup

Browse Source 
[ Upstream commit 43c2931a95e6b295bfe9e3b90dbe0f7596933e91 ]

Fix bug where make nconfig doesn't initialize the default locale, which
causes ncurses menu borders to be displayed incorrectly (lqqqqk) in
UTF-8 terminals that don't support VT100 ACS by default, such as PuTTY.
