stdio: suppress macOS 13 sprintf warnings
* lib/stdio.in.h (_POSIX_C_SOURCE, _GL_DEFINED__POSIX_C_SOURCE):
Suppress deprecation warnings for sprintf and vsprintf
that were introduced in macOS 13. These are not useful
for Gnulib itself, and are more likely than not to be
merely an annoyance for Gnulib-using code.
