runner: Clean up test logic.

This addresses some feedback in
https://boringssl-review.googlesource.com/c/boringssl/+/48131/1/ssl/test/runner/runner.go#1555,
pulled into a separate CL for clarity:

First, take the listener, waitChan, exec.Cmd trio and wrap them into a
shimProcess type. shimProcess is now responsible for the -port flag, so
it can manage the TCPListener internally.

Next, take the core test loop and moves it into a doExchanges()
function, so that it can use a more usual early return pattern for
errors, rather than thread err == nil through all the control flow. With
shimProcess pulled out, doExchanges() can just take a *shimProcess.

Finally, unacted-on err variable has gotten very far from where it's
actually used. Rename it to localErr, to align with our
expectedLocalError machinery.

BoringSSL

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.

Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.

Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.

BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.

Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
