[tsan] add data race suppression for avg_latency and send_latencyres …

[darnuria]

Attempt to add suppression for data races on send_latency and avg_latency globals. see discussion here #11814

[darnuria]

First time committed a tsan supp. I have seen that a change in https://github.com/PowerDNS/pdns/blob/master/.github/workflows/build-and-test-all.yml may be required but never committed Github workflow thing.

@rgascogne have to make a rebase/squash or you you do the rollup? :)

[rgacogne]

I'm not sure why the CI keeps failing on this one. Would you mind rebasing on master and squashing while you are at it? :)

Got something like:

And something ... without log in Run inv test-auth-backend -b authpy.

Done squash + rebase. Wait and see. :eyes:
