Disable symlinks: don't allow creating or truncating a file via a symlink in the last path component if "if_not_owner" parameter is used. To prevent race condition we have to open a file before checking its owner and there's no way to change access flags for already opened file descriptor, so we disable symlinks for the last path component at all if flags allow creating or truncating the file.
