replace fixed api-example files with generated ones

[bernhardreiter]

Found that old debdf6c inserted explicit example files, though the dynamic example files from the modules are different.

Should be fixed to use the example files that are created by the modules during build or install time, e.g. running

python3 -m events_api.events_api --example-conf

{
  "libpg conninfo":
    "host=localhost dbname=intelmq-events user=eventapiuser password='USER\\'s DB PASSWORD'",
  "database table": "events",
  "logging_level": "INFO",
  "subqueries": {
     "all_ips": {
       "sql": "(\"source.ip\" = %s OR \"source.local_ip\" = %s OR \"destination.ip\" = %s OR \"destination.local_ip\" = %s)",
       "description": "Queries (source|destination).(local_)ip",
       "label": "Query all IPs",
       "ext_type": "integer"
     }
   }
}
