Rename _job_wrapper to job_wrapper in two offending lines

Henrik went from using job_wrapper to job_wrapper_in as class argument.
As a consequence the variable _job_wrapper has been replaced with
job_wrapper.  Two lines in my added content needed to be changed to
reflect the renaming of _job_wrapper. Update the variable used in the
condor configuration script accordingly.

Changes:
	modified:   condor/manifests/client.pp
	modified:   condor/templates/condor_config.local.csnode.erb
