tipc: fix regression bug where node events are not being generated

Browse Source 
Commit 5902385a24 ("tipc: obsolete
the remote management feature") introduces a regression where node
topology events are not being generated because the publication
that triggers this: {0, <z.c.n>, <z.c.n>} is no longer available.
This will break applications that rely on node events to discover
when nodes join/leave a cluster.

We fix this by advertising the node publication when TIPC enters
networking mode, and withdraws it upon shutdown.
