Rules: hard code outrules.d location.  gnash teeth.

Well, poop.  The setuptools way just doesn't seem to work.  Use only
hard-coded paths and write a big complainey comment about how that's
messing up my /feng shui/.

setup.py: use correct path for data-files

Oops, the only reason the old path seemed to be working right was a bug
in my ebuild.  Correctly specify the full path under $prefix for the
installed files.
