msg.sock: is it really private dir, or a runtime/pid dir?

[Michael Tokarev]

I noticed msg.sock/ subdir is created within samba private directory,
and it contains sockets for various samba processes.  This smells like
it should be done in a runtime directory (/run/samba/) instead.

In the code, in source3/lib/messages.c, this is indeed done in private dir:

       priv_path = private_path("msg.sock");

I think the sockets should not be in a private state directory to start
with.
