posix_spawn_file_actions_addfchdir_np: return EBADF on negative fd
FreeBSD and Musl implement posix_spawn_file_actions_addfchdir_np
so that it checks the incoming descriptor for being negative, and,
if so, return with EBADF. The POSIX proposal defining
posix_spawn_file_actions_addfchdir follows this behaviour, see
https://www.austingroupbugs.net/view.php?id=1208
Fixes: 7e03fc35f528 ("Add posix_spawn_file_actions_add{f}chdir_np")
