posix: Add POSIX posix_spawn_file_actions_add{,f}chdir

Use proper symbols instead of alias to the *_np counterpart. The declarations are also moved from __USE_XOPEN2K24XSI to __USE_XOPEN2K24. POSIX.1-2024 defines both functions as part of the spawn option without XSI shading, so they must be visible under _POSIX_C_SOURCE=202405L (and with the default feature set) as well. Checked on x86_64-linux-gnu.
