Fix store creation of libimagstore 

The macro may not prefix the StoreId internal PathBuf with '/', so this
path is not absolute. This way we can introduce `storify_id()` which
creates a proper PathBuf into the store out of our StoreId object.

Does not yet do verification whether the path is inside the store,
actually.
