ci(android): libbox 从 NAS gitea 镜像取 sing-box 源码,绕开 github 不可达

build-android 失败根因:build-libbox.sh 第一步 git clone github.com/SagerNet/
sing-box,而 mac runner(经 pangolin 隧道)连不上 github(SSL_ERROR_SYSCALL,
exit 128)。windows 成功是因为它从 NAS 镜像取 sing-box.exe、不碰 github。

修:build-libbox.sh clone 改用 $SINGBOX_GIT(默认仍 github,本地开发不受影响);
deploy-client.yml 的 build-android 设 SINGBOX_GIT=http://127.0.0.1:13000/wangjia/
sing-box.git,经 runner 的 gitea relay 取 NAS 上的 sing-box 镜像(已用 gitea
migrate 从 github 拉好,含 v1.13.13)。与 windows 的 DESKTOP_BIN_MIRROR 同思路,
CI 不再依赖 github。
