cmd/go/internal/modfetch: avoid http lookup for non-domain paths

Before, if vgo saw import "appengine" it would incorrectly try to
look up https://appengine?go-get=1. Apply the usual domain-name
restriction (dot before first slash) as in plain "go get".

Because the old network lookup also used to loop incorrectly,
at least according to a bug report, test a nonexistent domain
name too.

Fixes golang/go#23967.
