Keep test daemons out of production's traces and database (#87)

The browser suite's daemon took its environment from the shell running
it, so a shell with OTEL_EXPORTER_OTLP_ENDPOINT set would have sent its
fixture scans to production's Tempo, and one with IPX_DATABASE_URL set
would have run the suite against production's database. Both are now
blanked for it. Production's traces carry
deployment.environment.name=production, which the dashboard filters on,
so a daemon run by hand stays out as well.
