vagrant: Fix basebox having corrupt docker-compose binary

Browse Source 
This fixes the vagrant based sandbox from not working. This was particularly
annoying to track down because of not having `set -x` in `setup.sh` but
what looks like xtrace output in stderr. The xtrace output on stderr
was actually from the `generate_certificates` container:

```

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.
```
I ended up doubting the `if ! cmp` blocks until I added `set -euxo pipefail` and
the issue was pretty obviously in docker-compose land.

```

```

Notice that `container_id` is empty. This turns out to be because
`docker-compose` is an empty file!

```
vagrant@provisioner:/vagrant/deploy$ docker-compose up --build registry
vagrant@provisioner:/vagrant/deploy$ which docker-compose
/usr/local/bin/docker-compose
vagrant@provisioner:/vagrant/deploy$ docker-compose -h
vagrant@provisioner:/vagrant/deploy$ file /usr/local/bin/docker-compose
/usr/local/bin/docker-compose: empty
```

So with the following test patch:

We can try again and we're back to a working state:

:toot:

Except that my results are not due to the way docker-compose is being installed
at all. After still running into this issue when using a box built with the new
install method I was still seeing empty docker-compose files. I ran a bunch of
experiments to try and figure out what is going on. The issue is strictly
in vagrant-libvirt since vagrant-virtualbox works fine. Turns out data isn't
being flushed back to disk at shutdown. Both calling `sync` or writing multiple
copies of the binary to the fs (3x at least) ended up working. Then I was informed
of a known vagrant-libvirt issue which matches this behavior, https://github.com/vagrant-libvirt/vagrant-libvirt/issues/1013!

Fixes #59
