Stop including out-of-tree kernel modules

This presents some practical problems:
- We'll almost certainly fail shim review and therefore won't be able to
  have secure boot
- Pre-installing these modules taints our kernel, which will be
  problematic for engagement with upstream
- These modules can be fragile (see for example
  https://invent.kde.org/kde-linux/kde-linux/-/work_items/618)
- Including these modules broadens the attack surface, worsening
  security.

As nice as it is to have an "everything and the kitchen sink" approach
to hardware support via these out-of-tree kernel modules, I think the
drawbacks to the project as a whole and all of its users outweigh the
benefits to the specific people who benefit here.

Fixes #618
