scripts: fail explicitly in updatedep.sh when gopath.proto exists
I had been dealing with these intermittent failures for a while and
finally figured out why. The real solution is making genproto.sh less
ugly but that won't happen for a while.

+ # gopath.proto is created by genproto.sh and it thoroughly messes
+ # with go mod.

if [[ $(go version) != "go version go1.12"* ]]; then
echo "expect Go 1.12+, got:" "$(go version)"
exit 255
