Merge ~hyask/autopkgtest-cloud:skia/lxd_remotes_kernel into autopkgtest-cloud:master

[Skia]

See bug #2067633 for a description of the issue we faced. This works around the problem for all future LXD remotes.

Won't this need updating when we upgrade the hosts from Focal? How will we remember to do that if I'm correct?

[Skia (hyask)]

The host have already been upgraded from Focal with the move to bos03, and are running Jammy.
The question remains still, what will happen when we upgrade to Noble?

I see multiple aspects there:
- First, this won't happen magically, so someone will be watching anyway.
- The package probably won't be found, so the cloud-init will fail with an obvious `apt` error.
- If by some magic it does exists, then it maybe won't even be a problem in itself, because it's "just a kernel", and if the machine boots and works, there might be no point worrying?
- Even if it installs **and** brings issues, again, a dev will be watching, and both the `git log` and comment will point to the LP bug to have the context.
- Last time, when I did the upgrade from Focal to Jammy, a lot of other stuff broke anyway, so I guess a bit of time will need to be spent on this anyway when going from Jammy to Noble.
