KVM test: Unattended - call preprocessor to kill vms

Preprocessing code was killing VMs too abruptly
at the end of the installation, so let's add an
additional kill_vm_gracefully to it, so it can
try to shutdown the VM using a shutdown command
first, which makes windows install much smoother,
and it doesn't disturb with kickstart installs.
