build: Package the modules prior to site generation. (#720)

The manifest plugin adds the automic (but deterministic) module name in
the packaging phase, not in the compile phase.
Therefor, the site plugin would fail with

```
Creating an aggregated report for both named and unnamed modules is not possible.
Ensure that every module has a module descriptor or is a jar with a MANIFEST.MF containing an Automatic-Module-Name.
```

as the core module now is on the module path by default.
