Go: move extractor smoke test into integration tests

The standalone `go/extractor-smoke-test` (run only from `go/Makefile`'s
`test` target) was redundant: its core invariant, that traced and untraced
extraction produce the same result, is already asserted by the
`test-extraction` integration test, whose traced and autobuild cases share a
single `test.expected`. The control-flow query it ran is covered far more
thoroughly by the CFG library test.

The only combination not reproduced was autobuild under build tracing, so add
a `test_autobuild_traced` case to `test-extraction` and delete the smoke test.
