Title: fix(router): docker build fails when apt archive is stale

The Docker Index build for deis/router started failing with:
```console
Get:33 http://archive.ubuntu.com/ubuntu/ precise-updates/main python-software-properties all 0.82.7.7 [23.5 kB]

Err http://archive.ubuntu.com/ubuntu/ precise-security/main libcurl3-gnutls amd64 7.22.0-3ubuntu4.7

```
`apt-get update` before the first apt command seems to fix this
in general.
