Josef Bacik deab6f55a2 tools lib traceevent: Handle NULL comm name
It is possible that a pid has no associated comm attached to it, although it
can still be passed to pevent_register_comm().

But if comm is NULL, it will cause strdup() to segfault. To prevent this
from happening, if comm is NULL use the default "<...>" name for the
pid.
