www/{nginx-devel,freenginx}: 3rd-party modules management
The nginx_upstream_check_module extra-patches no longer matched the
current sources, so builds with HTTP_UPSTREAM_CHECK enabled failed.
nginx-devel: refresh the ngx_http_upstream_round_robin.c extra-patch for
nginx 1.31; reuse the patch already carried by www/nginx.
freenginx: regenerate the round_robin extra-patch against freenginx's
sources, and add extra-patch-ngx_http_upstream_check_module.c which
replaces the module's use of the ngx_http_status_t 'count' member
(removed in freenginx) with a local variable.
