cmd/go: bad error about missing import

[rsc]

I deleted cmd/internal/str and tried to build cmd/link. I get

% go build cmd
link/internal/ld/main.go:37:2: cannot find package "." in:
/Users/rsc/go/src/cmd/internal/str
%

There is no mention of an import of ".", so the message should not mention "." either.

Change https://golang.org/cl/360615 mentions this issue: cmd/go: fix error message when missing import

https://golang.org/cl/360615 I am not sure if this change is correct, it seems that without modify test case file, I get an error when I run it.

  > ! go list -mod=vendor all
            [stderr]
            cannot find package "vendor/example.com/badedit" in:
                $WORK/gopath/src/vendor/example.com/badedit
            [exit status 1]
            > ! stderr '^go: inconsistent vendoring'
            > stderr 'cannot find package "\." in:\n\t.*[/\\]vendor[/\\]example.com[/\\]badedit$'
            FAIL: testdata/script/mod_go_version_missing.txt:30: no match for `(?m)cannot find package "\." in:\n\t.*[/\\]vendor[/\\]example.com[/\\]badedit$` found in stderr

It seems that should change this file.

Sorry，I can't run all.bash several days ago. I have updated this CL.
