No longer explicitly list addon files, instead copy all files from /boot/addons/

It's annoying to have to manually adjust the list of expected addons
whenever we add/remove files (like adding EFI-capable addon files,
what I'm currently working on). Especially since the grml2usb version
as present in Debian/Grml repositories might not match the Grml ISO
the user wants to use.
