Workhorse to serve the output for format-patch

Now this is done by Rails which is sad for the Unicorn worker, so this
is moved here. This commit excludes tests for now, which will be added
after the weekend.

Part of fixing: gitlab-org/gitlab-ce#13999

See merge request !48

Also a forgotten diff is now renamed to patch

Use docker go image

By using the official go docker image there is no need to install go
manually and this saves time pulling the ruby image which is not being
used anyway. Also, some time is save now not all packages need to be
installed to install Go.

At least thats what I expected when I typed the commit message, the speed gain is to be neglected though at least this yields a clean `.gitlab-ci.yml`.
