Python 3 - Fix some issues with class / instance variables in unittest2.

Explanation from a Python wizard (not me) about why this exhibited
different behavior under Python 2 and Python 3.

    `cmp` is a builtin_function_or_method in Python 2.7, which doesn't
    have a __get__ and doesn't qualify as a "descriptor".  Your lambda is a
    regular function which qualifies as a descriptor whose __get__ method
    returns a bound instance.

His suggested fix was to write

    sortTestMethodsUsing = staticmethod(cmp_)

However, I don't think `sortTestMethodsUsing` (or any of the other fields
of `TestLoader`) should be class attributes anyway.  They are all accessed
through self, so they should be instance attributes.  So the fix employed
here is to convert them to instance attributes.
