osdict: Re-purpose supports_unattended_drivers()

supported_unattended_drivers() was originally added as a way to tell
whether a guest could support pre & post installable drivers.

This is wrong for two reasons:
- virt-install cannot deal with post-installable drivers/agents;
- pre-installable drivers are the only ones needed in order to perform
  an unattended installation taking advantage of virtio-win drivers;

Knowing that, let's only check for pre-installable drivers in
supported_unattended_drivers().
