uutils coreutils: cp/install/mv/ln --suffix alone does not enable backup mode (silent data loss vs GNU)

`determine_backup_mode` in `src/uucore/src/lib/features/backup_control.rs` only checks `--backup`/`-b` and returns `BackupMode::None` when only `--suffix` is given. GNU enables backup mode when `--suffix` is used alone (defaulting to existing/numbered, or `$VERSION_CONTROL`). Affects `cp`, `install`, `mv`, `ln` which share this code. ``` # uutils: no backup created $ coreutils cp --suffix=.bak src dest # dest.bak NOT created # GNU: dest.bak created $ cp --suffix=.bak src dest ``` **Impact

uutils coreutils Missing TOCTOU Protection on Non-Linux Unix Platforms in Safe Traversal Module

The safe_traversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use (TOCTOU) symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets. On other Unix-like systems such as macOS and FreeBSD, the utility fails to utilize these protections, leaving directory traversal operations vulnerable to symlink race conditions.
