py3: make check-py3-compat.py load modules in standard manner Otherwise no code transformation would be applied to the modules which are imported only by imp.load_module(). This change means modules are imported from PYTHONPATH, not from the paths given by command arguments. This isn't always correct, but seems acceptable.
