After IGT migrating to dynamic sub-tests, the pipe prefixes
in the expected fails list are incorrect. Lets drop those
to accurately match the expected fails.

In addition, update the xfails list to match the current passing
list. This should have ideally failed in the CI run because some
tests were marked as fail even though they passed but due to the
mismatch in test names, the matching didn't correctly work and was
resulting in those failures not being seen.

Here is the passing pipeline for apq8016 with this change:
