Ah, I see what happened.  My script fetched the tar file from the
github release tag:

https://github.com/coreboot/coreboot/archive/4.5.tar.gz

Instead of fetching from the official release server:

https://www.coreboot.org/releases/coreboot-4.5.tar.xz

That's why the submodules are not included in the source tar.

What's the distinction between coreboot/src/vboot and the
coreboot/3rdparty/vboot directories?  As Peter pointed out,
having the necessary headers self contained in the coreboot
tree would be nice to have.
