Fix format string in bindings/go/llvm/ir_test.go (PR40561)

[hans]

Summary

The test started failing for me recently. I don't see any changes around this code, so maybe it's my local go version that changed or something.

The error seems real to me: we're trying to print an Attribute with %d. The test talks about "attribute masks" I'm not sure what that refers to, but I suppose we could print the raw pointer value, since that's what the test seems to be comparing.
