Add a objc_class_prefix to test_messages_proto3.proto.

Both test_messages_proto3.proto & test_messages_proto2.proto define
message ForeignMessage {...} and enum ForeignEnum {...} but since
objc doesn't use the proto package in the naming, these end up
conflicting.

Adding the objc_class_prefix option to the proto3 file ensure the generated
objc types are all unique.
