nginx-otel build fails on FreeBSD after `devel/protobuf` update to 24.4

[osokin]

Describe the bug

OTEL module build fails on FreeBSD 13.2 after devel/protobuf update to 24.4

Initially build fails with following error:

/usr/local/poudriere/ports/local/www/nginx-devel/work/nginx-otel-dc52126//src/http_module.cpp:8:10: fatal error: 'google/protobuf/stubs/logging.h' file not found
#include <google/protobuf/stubs/logging.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A trivial patch with removing the header file shows another error:
