Keep main's rule for which haves run inside the node's own composition

Review round 1: a have naming no build in a phase but running is also written for a
module that runs inside the node's own (waiting for a yes), so taking it out would
drop its resources before the yes. The fp the held have now keeps already fixes
postgres (issue 1289); a test drives an interrupted backup end to end.
