When trying to debug an issue on ARM64 it was reported that it was quite difficult to debug because of control codes on the console from the splash. For cloud image there is a chroot customization the drops 'quiet splash' but this is only applied to amd64. It hasn't made it into other architectures because they don't have grub by default in the chroot. However, when we get into binary hook for the uefi disk image and it's derivatives grub is installed and this includes architectures that were skipped in the chroot hook. This patch changes the cpc-fixes chroot hook to add a cloud-images grub config with basic overrides, including dropping the boot splash, for all architectures. For images that never get grub installed this addition is harmless and small while ensuring that the grub experience is consistent for images that have grub. The configuration of console devices as hard-coded remains arch specific.
