Use procsignal_sigusr1_handler for auxiliary processes. AuxiliaryProcessMain does ProcSignalInit, so one might expect that auxiliary processes would need to respond to SendProcSignal, but none of the auxiliary processes do that. Change them to use procsignal_sigusr1_handler instead of their own private handlers so that they do. Besides seeming more correct, this is also less code. It shouldn't make any functional difference right now because, as far as we know, there are no current cases where SendProcSignal targets an auxiliary process, but there are plans to change that in the future.
