warn_unused_result in pgbench

When building without thread safety, I get the following compiler

That should be fixed, I think.

We can stick a cast-to-void in there if that helps. Or we could have
the process exit(1) or exit(42) or something in that case. But then
pthread_join() would also need to get smarter, as would its callers.
