Thanks for your great help. A native recipe is what I needed with data in it
only. So my native recipe copies files into ${D}${datadir}/${PN}.
Then my image build uses DEPENDS= to bring in the native recipe.
Then my IMAGE_POSTPROCESS_COMMAND can reference
${STAGING_DATADIR_NATIVE}/[native recipe name] to find the data it needs.
Then I don't need to patch the bbclass file.

From first glance, I'd guess that the approach is just not correct. If
that thing to be fetched also needs to go *into* the image: make it a
recipe on its own. If you only need it during build time, then it should
probably be a -native dependency, and therefore again a recipe on its
own. Then the image recipe can depend on it and use its contents during
the build/postprocess stage.
