Subject: [PATCH] Ensure that grub-pc is installed in VMs even when using
 --nopackages

We're always setting up GRUB as bootloader when installing a VM.
If the --nopackages options is present the grub-pc package is
missing inside the VM. Therefore ensure that the grub-pc is still
present.

Fixes #40 @ github
