Go 1.20 finally includes proper support for instrumenting binaries for coverage. This allows us to drop quite a few hacks and workarounds that we used for it, and we can now also test exiting cases. The downside is that coverage tests now require Go 1.20, but it is an acceptable price to pay for the more accurate results. Normal integration tests are unchanged. This patch updates the coverage testing infrastructure to make use of the new Go 1.20 features.
