virtualizationservice: Unbind devices on VM exit

When configured to assign VFIO devices to a VM, virtualizationmanager
will bind them to the VFIO driver before starting the VM. This change
rebinds the default driver after VM exit, so the devices can be used by
the host again.

Test: Assign a device to VM, then check `<device_sysfs>/driver` post exit
