Apart from other uses, we need it because we are using composer
with vcs-repo to be able to use own instaclick, instead of getting
everything from packagist.
That hits Github's API limits and required OAuth tokens or similar,
easy to add locally, but not in CI envs like travis. So, only solution
is to make the php containers able to use the git alternative.
Apart from that, of course, having git within the images enables
some more dev workflows and really doesn't weights much.
