perf tools: Use same signal handling strategy as 'record' I.e. don't exit with the signal number, instead set the signal handler to the default one and then raise it again. Noticed while trying to dump the stack at segfaults in the 'perf test' forked process used to run each test, that inspects signal info at each test.
