[pxe] If no ProxyDHCPACK exists, use DHCPACK for the fake ProxyDHCPACK packet
WinPE seems to have a bug that causes it to always use the TFTP server
IP address and filename from the ProxyDHCPACK packet, even if the
ProxyDHCPACK packet doesn't exist. This causes it to end up
attempting to fetch a file such as
tftp://0.0.0.0/bootmgr.exe
If we don't have a ProxyDHCPACK to use, we pretend that it was a copy
of the DHCPACK packet. This works around the problem, and hopefully
won't surprise any NBPs.
