    Fix the lighttpd process recovery failure

    When the lighttpd starts without creating a pid file, SM will restart
    the process after the audit detects the failure. The init script
    then kills the current running process and starts a new one.

    The kill method was using the default port 80, as a result the
    process that was running without a pid file was not killed. Therefore,
    ‘Service group web-services degraded’ alarm was never cleared due
    to recovery failure.

    This update changes the kill method to kill the process that running
    on the configured lighttpd port.
