RFR: 8330302: strace004 can still fail

[David Holmes]

This is a trivial point fix for the `strace` tests to add in the missing event (super)constructors. These tests have started failing more regularly after the `Thread.sleep` code was recently changed.

The fragility of these tests is well known but I simply want to deal with current failures in our CI. It remains a future RFE to fix these tests so they don't need continual updating like this.

Testing:
 - themselves
 - tier 5 (which is where we see CI failures most often)

Thanks
