Title: HPCC-8395 Avoid MP issue, caused by new lookupjoin

Lookup join, has a couple of threads, both potentially sending
to the same destination on the same tag at the same time.
If these MP packets are deemed multi-packet by MP (which invariably
they will be), then the MP receiver gets confused and fires
MP protocol errors.
