fix #9368

[leonardo-albertovich]

Is this just a patch for that bit of code or was this the only part of protobuf-c.c that was modified at all?
Just to be clear, the idea is to update the entire file, not to backport changes.

@Crispy-fried-chicken Fluent Bit vendors in its libraries so we do not typically patch them in place but instead take updated versions from upstream.

In this case I think the issue is cmetrics using an older protobuf-c version so we need to update that in cmetrics, then bring in the new version of cmetrics to Fluent Bit: https://github.com/fluent/cmetrics

Also please update the PR name and commits based on the contribution guidelines - the DCO check is required to merge for example: https://github.com/fluent/fluent-bit/blob/master/CONTRIBUTING.md

@patrick-stephens so maybe I need to open a PR in https://github.com/fluent/cmetrics?
