VOL-4838 - makefile edits to cleanup permissions.

Makefile
--------
   o Added makefile target 'fixperms' that will strip group permissions
     from repository conf, json and yaml files.  This is a source for
     plenty of noise in the jenkins logs.
   o Added convenience target 'pre-commit' that will lint sources and
     repair permissions prior to creating a pull request.
