Increased package size in 8.11

gitlab-ce_8.9.5-ce.0_amd64.deb  267 MB

gitlab-ce_8.11.2-ce.1_amd64.deb 285 MB

```

The package received 20MB in size, and I don't recall us adding any new services/libraries


Could be the gems themselves?

We need to keep an eye on it in case it continues growing.
