Include the same drivers in the Live ISO as the installation-images do

[lslezak]

Problem

• We used our own logic to delete the not needed kernel drivers from the Live ISO
• We just deleted the multimedia drivers (sound card, TV cards...)
• That's a good starting point, but not enough

Solution

• The installation-images contains a more fine tuned list of the included drivers
• Copy the module.list file from i-i, process it by an updated script
• Add module.list.extra file for Agama specific tweaks and hot fixes (to keep the original i-i file untouched, that allows easy update of the file)

Testing

• Tested manually, the ISO build fine, the final image is 40MB smaller than before
