payloads: Force sub-make runs for in-tree payloads

The sub-process calls break make's dependency tracking, hence we have
to always perform the calls if we want to allow automatic, incremental
builds.

We let each rule depend on a new, phony target `force-payload`. It has
roughly the same effect as tagging all the targets as phony, but doing
so would feel wrong as some of them are actual files.
