build_image_util: generate package license list for each image

Browse Source 
There isn't a sane way for users to know the licenses of individual
packages in CoreOS images in built images. The information is hidden
away back in the original ebuilds. This extends our existing package
list with a new file that also includes licenses:

```
app-admin/flannel-0.3.0-r3::coreos Apache-2.0
app-admin/fleet-0.9.1::coreos Apache-2.0
app-admin/locksmith-0.2.3::coreos Apache-2.0
app-admin/sdnotify-proxy-0.1.0::coreos Apache-2.0
app-admin/sudo-1.8.10_p2::portage-stable ISC BSD
app-admin/toolbox-0.0.0-r4::coreos Apache-2.0
app-arch/bzip2-1.0.6-r6::portage-stable BZIP2
app-arch/gzip-1.5::portage-stable GPL-3
app-arch/tar-1.27.1-r2::portage-stable GPL-3+
...
```
