stdlib: Use __get_numeric_locale instead of __localeconv_l for decimal_point
...
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.

By previous commit, strto{d|ld} ("nan")
does not use the definition of NaN.
There is no other function that uses the definitions.
This commit remove the definitions.
