Add postinst and prerm to dpkg-divert unbound_munin_

This plugin is shipped in unbound in stretch, which causes a bunch of
issues.

Eventually, we should remove the plugin (and the divert) from here.

   * Add lvmcache_ plugin, for graphing lvm cache state 
+  * Add prerm and postinst to handle duplication of unbound_munin_ (also
+    provided by unbound in stretch).  Eventually we should move to that
+    plugin, but not until we're on stretch everywhere.
