ncm-metaconfig: support condrestart action

[ned21]

metaconfig only supports the actions restart, reload and stop_sleep_start. We require the condrestart action in some cases.

One such case is auditd: metaconfig is used to create the auditd config file during the installer. auditd is then started by virtue of having restart called. However the startup fails because the system install isn't complete yet, certain directories it wants to monitor have not yet been created. This spurious error could be avoided if metaconfig could be told to call condrestart instead of restart
