s4-messaging: Fill in the whole server_id in all use cases
This started per https://bugzilla.samba.org/show_bug.cgi?id=8872#c4
and avoids any possible collision with a different process.
We also need to ensure that across a Samba installation on a single
node that id.vnn is the same. Samba4 previously used 0, while Samba3
used NONCLUSTER_VNN. When a message is sent between these 'different'
nodes, the error NT_STATUS_INVALID_DEVICE_REQUEST is raised.
