tdf#105844 package: ODF wholesome encryption: use package version

... to init the Version property.

The problem is that the outer storage loaded from a wholesome ODF
encrypted document doesn't have a Version, because it doesn't (directly)
contain a document and has no "/" file-entry.

Extract the root element's package version attribute and use it.

The Storage API doesn't distinguish much between the package version and
the root document's (i.e. root folder's) version.
