fix(update): 更新前自动备份以 drouter 身份跑时写不进备份目录
真机报错：更新功能「备份失败，已中止更新」——
[Errno 13] Permission denied: /opt/drouter/backups/xxx.part。
根因：/opt/drouter/backups 是 root:root drwxr-xr-x，而「更新前备份」这条链
由 drouter-web（drouter 用户）spawn drouter-backupd.py --run-now，backupd 的
call() 用 subprocess 直接跑 helper、没提权 → helper 继承 drouter 身份 →
写备份包 .part 被拒。定时器那条链是 root 跑的，所以平时备份正常，
只有「更新触发的备份」踩雷。
修法：backupd 的 call() 里 helper 调用加 sudo -n 前缀。sudoers 已放行
drouter 免密跑 helper 白名单，root（定时器）/ drouter（更新）两种身份都通。
判据：t-update.py 新增「backupd call() 用 sudo -n 提权」（查命令数组语义），
t-update-inject.py 加对应反向验证注入（34 例 0 异常）。
真机验收：sudo -u drouter backupd --run-now → BK_CREATED files=21 size=23767。
