banip: update 1.8.8-5

* bugfix: only load the configuration once per run: a new `ban_confload`
  guard short-circuits `f_conf()` on subsequent calls, avoiding
  repeated `config_load` invocations
* new: the per-set report now sorts elements by their packet counter in
  descending order before truncating to the top 50, so the report
  shows the most active elements instead of just the first 50 found
