enable debug output for test_usdt3.py

test_usdt3.py has been flaky for a while. When the test failed, it looks like it did not catch a single event. The patch enabled debug output to print out all the trace points before attachments so we will have more context in case of failure. Also this debug output seems significantly reduced flakiness and in my fc28 I cannot reproduce the test failure with it. Signed-off-by: Yonghong Song <[email protected]>
