Subject: [PATCH 53/59] sysctl: Remove support for CTL_ANY

From: Eric W. Biederman <ebiederm@...ssion.com> - unquoted

There are currently no users in the kernel for CTL_ANY and it
only has effect on the binary interface which is practically
unused.

So this complicates sysctl lookups for no good reason so just remove it.
