Bump `shirou/gopsutil` to include https://github.com/shirou/gopsutil/pull/603
This will allow to have consistent node-id even when machine is reinstalled
when using `"disable_host_node_id": false`
It will fix https://github.com/hashicorp/consul/issues/4914 and allow having
the same node-id even when reinstalling a node from scratch. However,
it is only compatible with a single OS (installing to Windows will change
the node-id, but it seems acceptable).
