go vet can fail. It will be nice if we can run it in preupload hook, because developers can know the failure quickly.

Local experiment:

cd ${chromeosroot}/platform/tast-tests
GOPATH=${chromeosroot}/chroot/usr/lib/gopath:${chromeosroot}/src/platform/tast:${chromeosroot}/platform/tast-tests go vet chromiumos/tast/local/...

worked successfully on my local dev env at least.
