meta-ampere: usbnet: implement using usb-ctrl

Change to implement virtual USB Ethernet using phosphor-misc's usb-ctrl.

Tested:
1. Boot BMC to Linux. Login and check if usb0 ethernet interface exists.
2. Power ON the Host. Check if usb0 automatically sets its IP to
192.168.0.10
3. Restart the ampere-usbnet.service service. Check if no error happens.
