Debug Go attribute test

[haberman]

Summary

This test is failing in my other review https://reviews.llvm.org/D99517
but I'm having trouble figuring out why and I can't
reproduce the problem locally.

This change is intended to help understand if this
test is already failing, and if not to get some more
debugging output.

• Added import of fmt.

[dblaikie]

what's the plan? To commit this and check some buildbot logs to better understand how the test works to mitigate issues with your pending patch?

[haberman]

I created this to see what the buildbots would do, but my previous change managed to go in without it. I'll abandon this now.
