cmd/go/internal/modfetch: detect and recover from missing ziphash file Previously, if an extracted module directory existed in the module cache, but the corresponding ziphash file did not, if the sum was missing from go.sum, we would not verify the sum. This caused 'go get' not to write missing sums. 'go build' in readonly mode (now the default) checks for missing sums and doesn't attempt to fetch modules that can't be verified against go.sum. With this change, when requesting the module directory with modfetch.DownloadDir, if the ziphash file is missing, the go command will re-hash the zip without downloading or re-extracting it again. Note that the go command creates the ziphash file before the module directory, but another program could remove it separately, and it might not be present after a crash.
