Update Dockerfile

Use released binary file from github rather than build with static flag. this will make docker image's behavior as same as released binary file. and pack with static library flag will take up additional image space.
使用github上已经发布的二进制文件而不是使用静态链接库标志构建，这可以使docker映像的行为与release的二进制文件保持一致。并且，使用静态链接库标志，将占用额外的镜像空间。
