brew update

在linux上，不同发型版本有自己的包管理工具，如：

• ubunutu / debian => 使用apt
• centos / redhat /fedora => 使用yum或者dnf
• archlinux => 使用pacman

虽然使用方式上各异，但是大同小异，核心的问题在于软件的更新上，
一些版本为了追求稳定性，所以默认的软件仓库中的都比较老，
但是，对于开发状态来说 需要尝试新版本的特性

Mac上一般是用homebrew来进行软件的管理，使用体验非常优秀，软件更新非常及时，使用简单
能否统一Mac和Linux的软件管理体验，答案是ok，👍

homebrew支持linux和mac的平台，但是homebrew默认使用github作为软件源，国内访问比较慢
结合清华大学对于homebrew的镜像托管，起到了很好的速度提升。

此脚本自动化的实现 mac / linux 平台上的homebrew的安装和加速。
