crypto/tls: map boringssl errors to go errors in BoGo shim config

[rolandshoemaker]

The BoGo shim config has a field (ErrorMap) that allows mapping between BoringSSL style error strings to local error strings, which we should populate.

We currently don't map these, which can lead to failures being masked (see #70915).
