[dhcp] Do not skip ProxyDHCPREQUEST if next-server is empty
We attempt to mimic the behaviour of Intel's PXE ROM by skipping the
separate ProxyDHCPREQUEST if the ProxyDHCPOFFER already contains a
boot filename or a PXE boot menu.
Experimentation reveals that Intel's PXE ROM will also check for a
non-empty next-server address alongside the boot filename. Update our
test to match this behaviour.
