mod_firewall: Initialize compiled chunk just once for all handlers
This should fix a case where some stateful dependencies (such as throttles)
produce separate instances for every call to new_handler(), leading to
surprising behaviour (e.g. rules executed via JUMP CHAIN vs ::deliver would
have separate rate limits).
This also adds better error handling in case the compiled code fails to run
for some reason.
