files/fail2ban-openrc.init: use the standard OpenRC "retry" variable.

If the "retry" variable is set in the service script, we don't have to
pass it to start-stop-daemon explicitly. While we can't immediately
eliminate any code with this change, it will be necessary later to
adopt the default OpenRC stop() function.
