cmd/go/internal/modfetch: always check for a go.mod file when fetching from version control

If the module path declared in the go.mod file does not match the path
we are trying to resolve, a build using that module is doomed to fail.
Since we know that the module path does not match in the underlying
repo, we also know that the requested module does not exist at the
requested version.

Therefore, we should reject that version in Stat with a “not exist”
error — sooner rather than later — so that modload.Query will continue
to check other candidate paths (for example, with a major-version
suffix added or removed).

Fixes #33099
