ids.cgi: Restart suricata if necessary when altering the ruleset.

Suricata does support re-reading it's configuration files and therfore
we need to restart it, if one or more ruleset files should be loaded or
not loaded anymore.

If simple some rules inside the same files are activated or deactivated
we are still fine to call the reload method to send suricata the signal
to reload its ruleset.

Fixes #12340.
