tipc: fix regression bug where node events are not being generated
Commit 5902385a2440a55f005b266c93e0bb9398e5a62b ("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.
