dm: Add Oracle subsystem vendor ID

Browse Source 
After Windows 10, version 1607, the cross-signed drivers are forbiden
to load when secure boot is enabled.

Details please refer to
https://docs.microsoft.com/en-us/windows-hardware/drivers/install/kernel-mode-code-signing-policy--windows-vista-and-later-

That means the kvm-guest-drivers-windows can't work when secure boot enabled.
So we found another windows virtio FE drivers from Oracle to resolve this issue
but have to change another subsystem vendor ID for the virtio BE services.

This patch introduces a new DM CMD line "--windows" to launch WaaG with Oracle virtio devices including
virtio-blk, virtio-net, virtio-input instead Redhat. It can make virtio-blk, virtio-net and virtio-input
devices work when WaaG enabling secure boot.
