[PATCH 3/7][SYSVIPC] Use the ctl paths to register tables

[Pavel Emelyanov]

Theoretically, IPC sysctl variables may be in different 
namespaces and we have to register an appropriate ctl root
and new tables for each namespace.

On the other hand, the sysctl names do not differ from
namespace to namespace, and we already tuned the IPC
sysctl code to handle the multy-namespace variables. 

I think, that registering tables for each namespace is
just a waste of kernel memory and unneeded code. Thus, 
I just switch the IPC code to use the paths and keep 
current namespaces management code as is.
