Use Package qemu-system-x86 on debian

Ansible won't find the package qemu-kvm on my debian host. See Issue stackhpc#68
So I changed the package name to qemu-system-x86 and it works fine.

*(Tested with debian buster and bullseye)*

For Package Details, have a look at https://packages.debian.org/bookworm/qemu-kvm
