Subject: [PATCH] udev: expose USB 3.0 devices for PV USB

Even if particular PV USB implementation doesn't support it, still have
it included in QubesDB. It should be up to attaching code to decide.

Also, don't fail if xen-usbback module doesn't exist. This isn't the
only option (the other one is usbip over qrexec).
