[pxe] Populate ciaddr in fake PXE Boot Server ACK packet

We currently do not populate the ciaddr field in the constructed PXE
Boot Server ACK packet.  This causes a WDS server to respond with a
broadcast packet, which is then ignored by wdsmgfw.efi since it does
not match the specified IP address filter.

Fix by populating ciaddr within the constructed PXE Boot Server ACK
packet.
