stdlib: Use __get_numeric_locale instead of __localeconv_l for decimal_point

Browse Source 
The string/float conversion functions need to get the locale decimal
point. Instead of calling __localeconv_l (which copies locale data
into lconv form from __get_numeric_locale), use __get_numeric_locale
directly.
