py3: suppress unraisable exceptions in test-worker.t
Python 3.8 calls sys.unraisablehook when an unraisable
exception is encountered. The default behavior is to print a
warning.
test-worker.t was triggering this hook due to a race between
a newly forked process exiting and that process's
_os.register_at_fork handlers running. I was seeing the
stdlib's random module in the stack re-seeding itself. Although
there could be other after-fork handlers in the mix.
This commit defines sys.unraisablehook to effectively no-op.
This suppresses the warning and makes test output on Python 3.8
consistent with prior versions. test-worker.t now passes on
Python 3.8.
