Subject: [PATCH] Alter the args for apt-get in func `install_wg_3`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Do not install recommended packages while installing the `wireguard-tools` on a Debian-based OS running kernel newer than 5.6
当在内核版本大于 5.6 的 Debian 系发行版上使用从 repo 安装 wireguard 功能时，调整 apt-get 参数，使之不再主动安装 `wireguard-tools` 包列为 `建议` 包的其他软件包。

改动理由：
`wireguard-tools` 包下列为 `建议` 包的软件包包括 `wireguard-modules`，但是该套件暂时不可用，因此会安装 `wireguard-dkms` 代替。但在内核版本大于 5.6 的发行版上，安装 dkms 是不需要的，甚至会在更新 wireguard 时因为尝试更新 dkms 弹错误信息（这个无伤大雅，因为安装脚本只是检测到内核版本太新，警告用户 dkms 模块无需更新而已）
