Ticket 47513 - Refine the check for @localrundir@

Bug Description:  if @localrundir@ is not set, then the wrong value is used for tmpfiles.d

Fix Description:  Improve the checking/setting of the localrundir.  set_path_attribute() is not
                  the correct subroutine to call as it can incorrectly add the prefix again
                  if @localrundir@ is not set.  Created new function to just add the prefix -
                  only if @localrundir@ is set.
