cmd/go: always log dynamic import errors

There is no easy way to understand what user intent was and whether
they wanted to use a dynamic import or not.

If we skip logging such errors, it breaks common use cases such as
https://golang.org/issue/12810.

It's a better approach to expose the underlying mechanism and
be more verbose with the error messages.

Fixes #12810.
