py3: add extra traceback line present on Python 3.8

I'm not sure why Python 3.8 is outputting this line. It
appears to be a change in behavior of formatting tracebacks on
Python 3.8. So let's add it to expected output.

With this change, test-hook.t now passes on Python 3.8.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
