Fixes issue #7187. Thanks, Dave Malcolm for the report and analysis of the
problem.

Keeps benchmark faster by putting a cap on total execution time. Before a run
using importlib took longer by some factor, but now it takes roughly the
same amount of time as using the built-in __import__.
__package__, it was used. This was incorrect since it could be set to None to
represent the fact that a proper value was unknown. Now None will trigger the
calculation for __package__.

test_builtin against importlib.
This exception change is specific to importlib.__import__() and does not apply to
import_module() as it is being done for compatibility reasons only.
The file must be run using runpy. Certain tests are currently excluded from
being run as they have known failures based on golden value checks that fail
for various reasons (typically because __loader__ is not expected to be set on
modules). Running the tests with this file does discover some incompatibilites
in importlib that will be fixed in the near future (as noted currently in the
docstring).
