libgo: add "vendor" to pkgpath for vendored standard packages
Ensure that the packages vendored into the standard library do not
have the same pkgpath as the actual packages. If we don't, attempts

error I was seeing was import loops, causing some of the packages to
fail to get initialized, causing an obscure run time crash.

If somebody writes
func (s []int) _() {}
we should report an error. Before this patch we were silently
accepting this code, because we didn't report any errors about the

This patch is unfortunately slightly complex to handle the case of
func (x int) _() {}
