posix: Add POSIX aliases to some spawn functions

Browse Source 
Both `posix_spawn_file_actions_add{,f}chdir` functions are now fully
defined by POSIX-2024, this patch adds both functions as aliases of the
already existing `posix_spawn_file_actions_add{,f}chdir_np` GNU
extensions.

This makes glibc more compliant in regards to POSIX-2024.
