Injects the current sys.path into lint.py subprocess env

Browse Source 
This allows installing pylint in a buildout setup and *see* the eggs in the
buildout.  Since buildout modifies the installed scripts (like epyling) by
prepending and assignment to ``sys.path[0:0]`` all the eggs, we need to make
sure those path are the ones seen by pylint.
