proc: Fix the namespace inode permission checks.
Change the proc namespace files into symlinks so that we won't cache the dentries for the namespace files which can bypass the ptrace_may_access checks. To support the symlinks create an additional namespace inode with it's own set of operations distinct from the proc pid inode and dentry methods as those no longer make sense. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>
