The `FOLLOW_SYMLINKS` flag was added to the dir-iterator API infa1da7d2ee(dir-iterator: add flags parameter to dir_iterator_begin, 2019-07-10) in order to follow symbolic links while traversing through a directory. `FOLLOW_SYMLINKS` gained its first caller inff7ccc8c9a(clone: use dir-iterator to avoid explicit dir traversal, 2019-07-10), but it was subsequently removed in6f054f9fb3(builtin/clone.c: disallow `--local` clones with symlinks, 2022-07-28). Since then, we've held on to the code for `DIR_ITERATOR_FOLLOW_SYMLINKS` in the name of making minimally invasive changes during a security embargo. In fact, we even changed the dir-iterator API inbffc762f87(dir-iterator: prevent top-level symlinks without FOLLOW_SYMLINKS, 2023-01-24) without having any non-test callers of that flag. Now that we're past those security embargo(s), let's finalize our cleanup of the `DIR_ITERATOR_FOLLOW_SYMLINKS` code and remove its implementation since there are no remaining callers.
