nixos/slurm: set slurmd KillMode to process

Browse source 
The default of systemd is to kill the
the whole cgroup of a service. For slurmd
this means that all running jobs get killed
as well whenever the configuration is updated (and activated).

To avoid this behaviour we set "KillMode=process"
to kill only slurmd on reload. This is how
slurm configures the systemd service.
