Fix build

https://github.com/protocolbuffers/protobuf/releases/tag/v25.3

Also clean up protoc resolution.

@eed3si9n after this change, I can no longer zincPersistCore / Protobuf / protobufRunProtoc, either in the community build (where I noticed the problem) or locally?

@SethTisue Are you on some branch? On e902ec9 it works fine on my machine:

yeah I'm at e902ec9

and hmm, well, it still fails in the community build (both on Jenkins and locally), but it doesn't fail for me locally anymore outside of dbuild. I don't know what to make of it

I'll poke at it some more, I guess
