Philip Roche e65a499069 fix: Set the required debconf settings to allow for non interactive grub updates in cloud images (LP: #2054103)
As part of addressing LP: #2054103 [1] an update to grub-pc added a feature to be able to ensure that grub-pc
installation can happen noninteractively on cloud images.

This change is equivalent to running

```
debconf-set-selections grub-pc grub-efi/cloud_style_installation boolean true
debconf-set-selections grub-pc grub-pc/cloud_style_installation boolean true
```

These were introduced optionally to determine the install device using
`grub-probe` dynamically instead of having to fill the `grub-pc/install-devices`
debconf entry.
