Fix typo and full path issue

Previously, the JtR library was prepending the path to data/john/ for
shipped bins; without it, modules weren't finding the executables.
Use All4 instead of LanMan

... Which was the original behavior. A full incremental LanMan can take
many hours instead of the few seconds this module was intended to run.
Fix running shipped bins by using a config file

This should get everything working again.
