Upgrade pulumi-go-provider (#268)

Fixes https://github.com/pulumi/pulumi-docker-build/issues/262.

@iwahbe I realized while putting this together that the provider config
case wasn't actually tested e2e, and I'm skeptical it was ever actually
working. I think it would be reasonable to pull in
https://github.com/pulumi/pulumi-docker-build/pull/253 IMO.
