grpc_gateway_proto_library expects Gateway service definition for all proto files

[th0br0]

A target such as

grpc_gateway_proto_library(
    name="gateway",
    verbose=1,
    protos=["a.proto", "b.proto"],
    visibility=["//visibility:public"], )

Will expect output to

a.pb.gw.go
b.pb.gw.go
a.pb.go
b.pb.go
gateway.pb.descriptor_set

even though not all supplied proto files might contain valid (Gateway) service definitions.
If, for example, b.proto only contains messages, then no b.pb.gw.go output file is created by protoc
