perf evlist: Send the errno in the signal when workload fails
When a tool uses perf_evlist__start_workload and the supplied workload fails (e.g.: its binary wasn't found), perror was being used to print the error reason. This is undesirable, as the caller may be a GUI, when it wants to have total control of the error reporting process. So move to using sigaction(SA_SIGINFO) + siginfo_t->sa_value->sival_int to communicate to the caller the errno and let it print it using the UI of its choosing.
