init: configure "Non-Interactive Users" as batch priority

The Non-Interactive Users used to be a special group in the
system_config table to force its members onto the batch queue.
This default behavior was lost somewhere when priority settings
moved to project.config in All-Projects.

Restore the default for this group to use batch priority.
