#17375 Updating the osquery flags for 5.12.2 And making the changes so that we can just run `cd server/fleet/ && go generate` on a macOS host every time we need to do this. Manual tested by setting `logger_tls_backoff_max` in Fleet agent settings (which is a 5.12.0 flag). - [X] Changes file added for user-visible changes in `changes/`, `orbit/changes/` or `ee/fleetd-chrome/changes`. See [Changes files](https://fleetdm.com/docs/contributing/committing-changes#changes-files) for more information. - [x] Added/updated tests - [x] Manual QA for all new/changed functionality --------- Co-authored-by: Victor Lyuboslavsky <victor.lyuboslavsky@gmail.com>
