Applying patch #100994 to allow JPython to use more of the standard

Python test suite.  Specifically,

- import time instead of strop in test_b1

- test for ClassType of exceptions using isinstance instead of
  equality in test_exceptions

- remove __builtins__ from dir() output in test_pkg

test_pkg output needs to be regenerated.
