Running SITL with the Gazebo bridge under ThreadSanitizer reports many data races inside libzmq and gz-transport (and the GZBridge glue) - third-party simulation transport that is not in the flight path or the SIH-based CI and that we cannot fix. Add a suppressions file so the TSan signal stays usable for finding real races. Use via TSAN_OPTIONS="suppressions=test/sitl_tsan.supp".
