plnsub: Let crewless planes spread the plague, too

Commit 612ec62 (v4.3.31) made plane crew and cargo spread the plague.
This requires looking for crew in build materials.  Awkward if we ever
permit non-military crew.

Simply drop the "has crew" condition.  If a plane's cargo can spread
it, then servicing and refueling the plane can spread it, too.
