usb-ctrl: Add support to set BMC and Host's mac address
By default it uses the random MAC address when usb ecm is enabled.
Inspired from usb-network.sh in meta-quanta, it is possible to specify
the MAC address.
Add optional arguments to set the MAC address when ecm is enabled, so
that the BMC and Host side's MAC addresses are known.
Tested: Verify the MAC addresses could be specified by below command:
usb-ctrl ecm usbeth0 on <bmc-addr host-addr>
