util/smmstoretool: explain what happens when no store is found

We are going to expose ths tool to end users, and want to take
care that the presented information can be consumed by them.

The current code simply prints below warnings if we use release
binary available for end-user to download:

No firmware volume header present
No valid firmware volume was found

It will be concerning and not clear to end users, they might not
understant why it happens, what are the implciations, and whether
it is something that they should worry about.

This commit tries to explain what actually happens here.
