[libvirt] [PATCH 2/9] xenconfig: add support for multiple USB devices syntax

In Xen>=4.3, libxl supports new syntax for USB devices: usbdevice=[ "DEVICE", "DEVICE", ... ] Add support for that in xenconfig driver. When only one device is defined, keep using old syntax for backward compatibility. Adjust tests for changed options order.
