intel/metadata: pretty print specific key manifests

[orangecms]

This allows for better distinguishing them.

Note: I cannot get the manifest codegen to work in a Go module, so I manually made the changes as I understand it. Someone please verify.

It looks like manifestcodegen is broken by #394

The way you could use it is:

cd `go env GOPATH`/src/github.com/linuxboot/fiano/pkg/intel/metadata/cbnt
git remote add orangecms https://github.com/orangecms/fiano
git checkout print-as-key-manifest
GO111MODULE=off go run ./../common/manifestcodegen/cmd/manifestcodegen/ . ./cbntbootpolicy ./cbntkey

But it currently does weird stuff like this:

-       "github.com/linuxboot/fiano/pkg/intel/metadata/cbnt"
+       "github.com/linuxboot/fiano/pkg/intel/metadata/TODO_PACKAGE"
        "github.com/linuxboot/fiano/pkg/intel/metadata/common/pretty"

I'll fix this :(

Also https://github.com/linuxboot/fiano/blob/main/pkg/intel/metadata/README.md wasn't updated after #394 .

Let's merge this PR as is, and the codegen I'll tackle soon.

That might be a bug I introduced @xaionaro
