Fix make rebuilds for openapi

openapi generates a single file, so its rules can be significantly simpler.

federation generates an empty file which we previously elided, but which triggers deps every build.

This fixes both.

@mbohlool something to think about.  Generating a single file means you generate everything every time any tagged package changes.  This is not awesome.  In practice, it's pretty fast, so maybe just for thinking about - would it be better to generate a file for every tagged package, and only regenerate when needed.  The file could self-register a callback or just add some structs to your mega-map.
