pkgcache.cc: Mix PACKAGE_VERSION into the cache hash
This ensures that caches build with one version can't be
opened with another, which makes sense. It's a temporary
approach until we can replace major:minor fields with
a version string.
For example, this would have prevented 1.9.7 from using
broken caches from 1.9.6.
