files/fail2ban-openrc.init: replace FAIL2BAN with standard OpenRC variables.

The FAIL2BAN variable in our OpenRC service script was a combination
of two standard OpenRC variables, "command" and "command_args". This
commit simply replaces the custom variable with the two standard
ones. This will aid future simplifications of the service script.
