[Python-3000] Small Py3k task: fix modulefinder.py

[Guido van Rossum]

Is anyone familiar enough with modulefinder.py to fix its breakage in
Py3k? It chokes in a nasty way (exceeding the recursion limit) on the
relative import syntax. I suspect this is also a problem for 2.5, when
people use that syntax; hence the cross-post. There's no unittest for
modulefinder.py, but I believe py2exe depends on it (and of course
freeze.py, but who uses that still?)
