Add git version suffix to package name

[msaroufim]

fixes #546

Problem

It's not clear when you install ao looking at the version number if it was installed from source or not

This PR

We add the latest commit ID of the current branch to the name. So you can unambiguously tell if ao is installed from source or not by checking if there's a +git in the name

I'm not sure if this breaks internal in some mysterious way and I think this is safe as far as naming official binaries go
