neuron and cortex are independent packages installable on different
hosts. Having neuron run under a 'cortex' system user implied a
shared identity that doesn't exist. Give neuron its own user/group.
- New data/neuron-sysusers.conf declares the neuron user/group with
home /var/lib/neuron.
- systemd unit User/Group changed to neuron.
- Spec file attrs, explicit Provides, and %sysusers_create_compat
updated to reference the neuron user.
