Aligned systemd service config with the definition in the upstream repo: https://github.com/Irqbalance/irqbalance/blob/master/misc/irqbalance.service#L7. Other than adding some level of sandboxing it also fixes the "Daemon couldn't be bound to the file-based socket." warning reported on irqbalance startup due to the fact that the "/run/irqbalance" directory didn't exist. The "RuntimeDirectory" property makes sure it gets created. The aforementioned warning didn't cause any problems I could spot though. I have verified that both `irqbalance` as well as `irqbalance-ui` work fine with this new systemd service config.
