go/internal/load: fix bad error message for local imports in module mode

[Yuuki77]

In module mode, if an import statement refers to a relative path it is
currently supposed to fail with relative import not supported
However, we seem to be missing test coverage for that error message,
and the actual error that is printed for that case is substantially different

Fixes #47088
