Raspberry PIs need an updated git

[orangemocha]

The Raspberry PIs are failing node-accept-pull-request, because of the same issue we saw before on Ubuntu: #148

According to @joaocgreis, there is already a new version in the repositories, and all we need is to run:
apt-get update && apt-get install git

@rvagg : could you try that or give me and @joaocgreis access? Thanks!

git is at 1.7.10.4 on all of these machines, there's no update available on top of that, this is Raspbian fwiw
