cmd/go: update private copy of goosList

This copies the change to goosList in CL 138115 to the private copy in
cmd/go.

The change introducing the private copy was apparently not made with
Gerrit, but can be seen at
https://github.com/golang/vgo/commit/08359e782fb601567c57f56beb540841c2416d92.
That change says "This is adapted from code in go/build and the rest
of cmd/go. At some point, we should deduplicate them."

Doing another copy for now, rather than something more complex
involving cmd/dist, pending that deduplication.
