strace: Don't print exception info for SetThreadName exception 

The new functionality to set the thread name for debugging purposes
creates exception debugging events.  These are printed out when running
strace.  Since these exceptions have nothing to do with real exceptions
but are, like breakpoint execptions, expected and non-fatal, don't print
exception info for them.
