Description of changes:

storewolf: declare dependencies on model and defaults files

Without this, you can change a defaults file and not haven those changes in a
new build, or change the variant and still use the prior cached model link.

I believe this should also address the rare file-not-found issue seen in #1303 and in the checks of a couple PRs after.

Testing done:

Before, I built a k8s AMI and it was fine, but then I built an ECS AMI and it had the wrong model, spewing lots of errors about deserializing the incorrect data that storewolf had put in the data store. (@etungsten originally reported this behavior and I verified.)

After, I built a k8s AMI and it was fine, and then I built an ECS AMI and it was also fine, with the correct ECS settings.

Also confirmed that changes to the defaults files now rebuild:

• cargo make build-packages
• cargo make build-packages again; it did not rebuild os.
• touch 10-defaults.toml, cargo make build-packages, it does rebuild os.

Can you confirm by checking the output of the os package build that the storewolf crate is not "fresh" and gets rebuilt after touch 10-defaults.toml?

@bcressey I confirmed that a no-change rebuild gives me a "Fresh storewolf" and after touching 10-defaults.toml I get "Compiling storewolf".
