Bug#1092949: debian-installer could propose installing linux-image-cloud when run inside a VM

[Gioele Barabucci <gioele@svario.it>]

Package: debian-installer
Version: 20241227

Dear debian-installer developers,

currently d-i installs `linux-image-$arch` regardless of the kind of 
machine it is installed on.

When used inside a virtual machine, it could make sense to ask the user 
if they want to install linux-image-cloud-$arch instead, as it comes 
with a reduced set of modules and dependencies and fits better the needs 
of modern VMs.

Detecting whether d-i is running inside virtualized environment could be 
done using `systemd-detect-virt` or `dmidecode --string 
processor-manufacturer`.

Regards,
