core/legal-info: add package version to license directory

Now that we save the source archives in a directory named after the
package and its version, do the same for the license files, for
consistency.

It has a not-so-bad side-effect of also saving the version string in
the all-licenses list.

The only (small) side-effect, is that the warnings about undefined
_LICENSE_FILES now contains the version string, too. That's unavoidable,
since that's what is stored in the legal report.
