nixos/librenms: regenerate caches after every package change

The LibreNMS cache may contain paths to the old package and may break
when the old package is removed. So it is not enough to clear the cache
only on version updates, as the package will also change when build
inputs change.

This commit updates the setup script to regenerate the cache on every
package change. In addition, it now only performs migrations when the
package version has changed, since the migrations only change on version
updates and don't need to be applied on every package change.
