Drop node-engine's optional verb pull-waits: no record gives the seat that verb

The lead's ruling (14:2x): the pull waits ENG-9 shows are carried in the engine's have, read through node_haves, as
ENG-9 allows, so the seat serves no verb of its own for them. Regenerated; seatgen -check finds nothing out of step.
