Unable to build skicka because of grpc-go error

go get fails on my environment because of grpc-go.

$ GOPATH=$PWD /usr/lib/go-1.9/bin/go get github.com/google/skicka
# google.golang.org/grpc/internal/credentials
src/google.golang.org/grpc/internal/credentials/spiffe.go:34:70: state.PeerCertificates[0].URIs undefined (type *x509.Certificate has no field or method URIs)
