CoreDumpSvc: Add printout on calling previous signal handler

Add printout when calling the previous signal handler to help debugging missing stack traces seen in ATR-20796. Also change the exit code in case of recursive signals to 98 to distinguish it from the 99 exit code for "regular" crashes.

Note that the std::cout usage is unavoidable here as it's printing from a signal handler.
