mail-mta/nullmailer: remove '+=' bashism from init.d script

Noticed as a sourcing failure on a system with 'sh' ->/bin/dash:
    dash: 9: /etc/init.d/nullmailer: start_stop_daemon_args+= --stdout /var/log/nullmailer/nullmailer.log: not found
    dash: 10: /etc/init.d/nullmailer: start_stop_daemon_args+= --stderr /var/log/nullmailer/nullmailer.log: not found

Package-Manager: portage-2.3.2
