banip: update 1.8.5-2

* fixed two issues in the mail template, reported in the forum
* tweak the f_report function
* changed the f_actual function to reduce subshell calls
* further optimize the monitor function:
  * fixed a possible RDAP rate-limit race condition,
    serialize the rdap_tsfile via flock
  * block_cache bounded growth, when the cache reaches 500
    entries it resets to empty, preventing unbounded string growth
    in the monitor loop
* set the printf format string in single quotes (overall)
