ci: temporarily disable FreeNginx CI due to lua-nginx-module compatibility

FreeNginx commit 3329aa9d66 introduced breaking changes that cause
lua-nginx-module build failures. The commit replaced start_sec/start_msec
fields with a single start_time field using monotonic time.

Temporarily commenting out all FreeNginx CI steps until the compatibility
issue is resolved upstream.
