treebuilder: Add branding package to template variables

Browse Source 
The branding package name doesn't always match the product name.  This
saves the branding package names as discovered in the enabled repos and
exposes it to the templates as branding.release and branding.logos --
which could potentially be None so the template needs to take that into
account.
