Julie Qiu 51a47b7ff2 cmd/go: display helpful error when module cache can't be created
Previously when the module cache specified by GOMODCACHE could not be
created an unhelpful message would be printed multiple times.

This happened because we were fetching several things in parallel then
failing to write them because we can't create the module cache.

We now check if the module cache can be created before fetching.

If not, the following message is printed:

go: could not create module cache

Fixes #45113
