Unconditionally set GRUB_FORCE_PARTUUID in cloud images; as of version

Browse Source 
2.02+dfsg1-5ubuntu5 grub will automatically fall back to booting with an
initrd if one is available, so we can now always attempt initramfsless
boot for cloud images which almost always works and causes only minimal
increase in boot speed for cases where it does not.
