Dear Maintainer,

mmdebstrap-autopkgtest-build-qemu can be used to build Debian VMs, but
it fails to build Ubuntu VMs. I have locally patched it until it worked.
These three changes were needed:

1. The kernel package is called linux-image-generic instead of
   linux-image-amd64 on Ubuntu.

2. The symlinks vmlinuz and initrd.img do not exist in / but in /boot.

3. No initrd generator is installed. So mmdebstrap-autopkgtest-build-qemu
   should install dracut for Ubuntu >= 25.10 and initramfs-tools for
   Ubuntu <= 24.04.
