Track splitting of nsc-puppet-utils module.

We used some definitions, resource types and facts from the module
nsc-puppet-utils.  That module has been refactored, renamed to
"nscutils", and split into multiple modules, so we need to track
those changes.  We use resource types and definitions for editing
config files, which have been moved to the new module "cfgfile",
and the custom fact 'initsystem', which at the moment is still left
in the "nscutils" module.
