New GRUB2 config modules are causing issues on Atomic Desktops systems
as the new GRUB2 config get regenerated with new options that are not
supported by the currently installed version of GRUB2.
The root cause is that we don't (yet) systematically update the
bootloader on Atomic Desktops. This is related to:
https://gitlab.com/fedora/ostree/sig/-/issues/1
Temporarily remove / modify those config modules from the GRUB2 set of
configs used to generate the final GRUB2 config, until we are able to
enable bootloader updates by default.
