stdio.h: Don't define unlocked macros using static inline on C++ 

In C++, the usage of static inline functions for getchar_unlocked and
putchar_unlocked may result in error messages like

  error: ‘_putchar_unlocked’ was not declared in this scope

Fix this by not using the _getchar_unlocked and _putchar_unlocked
macros in C++.
