I'm not aware of a way you can do this, other than upgrading the Guava in Solr itself.
Or rather, you'd need to create your own classloader and load your own instance of Guava using that rather than the default classloader. That's possible, but would be rather ugly and complex. I'd say research what's required to upgrade the Guava in Solr.
