libevent HTTP benchmark never frees event_config

[OneBucket126]

Summary

event_config_new() allocates cfg. After event_base_new_with_config() the config can be freed, but the benchmark never calls event_config_free() on success or failure.

Impact

The configuration object remains allocated for the full benchmark process, including early-return paths.
