Description: the legacy ratelimit message is selectively used, so it is not linked by default. Previous to #4233 we had forced linking. In #4233 linking was forced while running tests, but --understandably so -- not in production code. This means that when this path is executed on a compiled binary, we would get a segfault due to a failure to resolved the service_method_ here.

Risk Level: medium, fixes a crash
Testing: Fixed the concrete repro showing the invalid reference on gdb, turn into a valid reference.

I think pgv_cc_proto_library does set alwayslink=1. I remember looking at the RLS test when putting together #4233 and thinking this was just some anomaly from the build deps and use of reflection. This seems fine for code that is going to be removed soon anyway.
