* xutils.py:
  - make isDriverInSection() return True only if all of the specified
    sections contain the driver. This prevents isDriverEnabled() from
    returning false positives.
* 1-test.py:
   - Modify the test for testIsDriverEnabled() so as to test the correct
     behaviour.
   - Add two more tests for IsDriverEnabled().
