cmd/go: fix tests when go.env sets GOPROXY=direct GOSUMDB=off
Tested locally by changing GOROOT/go.env. At some point perhaps we
should also set up a builder that runs with some common expected
modifications to go.env
(such as GOTOOLCHAIN=local GOPROXY=direct GOSUMDB=off).
Fixes #61358.
Updates #61359.
