It was found out that autopkgtests didn't pass the NOW env variable
which is generally provided by the launchpad-buildd build and thus
the autpkgtests fail.
ubuntu/include.* are the master location for these files.
Copy them over for projects with similar needs, while skipping ones that
are incorrect.

Ubuntu MATE is switching to a layered image in preparation to
use ubuntu-desktop-provision. Luckily, their seed structure is
already well-structured for layering, so this is easily done.
This has become moot now that the code block has been
moved out from live-build/functions to live-build/auto/build
so passing the argument is not needed anymore.
Presence of this field helps in determining if the image is an
unminimized image, which then can be leveraged in the unminimize
script to easily determine the image type.
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.

There was a time historically where Launchpad buildd might have relied
on that behaviour, but this shouldn't be the case anymore as it sets
priority manually when building backports.
Meanwhile any other builds using buildd images (e.g. snapcraft)
shouldn't default to backports unless required. (lp: #2009871)
