修复 v2ray/v2ray-core/issues/1909
实现原理
Go 的程序启动后，会读取
/etc/resolv.conf内的 DNS，用于域名解析的net.DefaultResolver变量会使用这些 DNS默认情况下所有域名解析相关的函数都会使用
net.DefaultResolver，其他项目也会使用这个，比如已存在的 QUIC 包由于 Android 并不存在
/etc/resolv.conf，Go 语言使用了它的默认值127.0.0.1:53地址作为 DNS 服务器，但 Android 也同样不存在这个 DNS 服务器这时
net.DefaultResolver内的 DNS 地址为127.0.0.1:53所以在 Android 操作系统中运行二进制程序会出现域名解析的问题
由此，此 PR 为 Android 系统替换默认的
net.DefaultResolver，为其设置 DNS8.8.8.8:53编译时按照文档编译即可
