build: test binaries are always stripped due to behavior of rules_go

[rickystewart]

It is impossible with rules_go to build an unstripped test binary. This is behavior that was adopted in bazelbuild/rules_go@9bbe81f. There is no command-line flag or similar that you can apply to disable this behavior. This should either be fixed upstream, or if it cannot, we should apply a patch to our fork that exposes the option.
