libc/fts: Use O_CLOEXEC for internal file descriptors

Because fts keeps internal file descriptors open across calls, making such
descriptors close-on-exec helps not only multi-threaded applications but
also single-threaded applications.

In particular, this prevents passing a temporary file descriptor for saving
the current directory to processes created via find -exec.
