Some sysctl tables are registered for each namespace.
(Like in ipc/ipc_sysctl.c)
These need special handling to track the variable assignments.

The script expects the old sysctl_register_paths() API which was removed
some time ago. Adapt it to work with the new
sysctl_register()/sysctl_register_sz()/sysctl_register_init() APIs.

This is part of the general push to deprecate register_sysctl_paths and
register_sysctl_table. After removing all the calling functions, we
remove both the register_sysctl_table function and the documentation
check that appeared in check-sysctl-docs awk script.
We save 595 bytes with this change:

The deprecation for register_sysctl_paths() is over. We can rejoice as
we nuke register_sysctl_paths(). The routine register_sysctl_table()
was the only user left of register_sysctl_paths(), so we can now just
open code and move the implementation over to what used to be
to __register_sysctl_paths().
The old dynamic struct ctl_table_set *set is now the point to
sysctl_table_root.default_set.
The old dynamic const struct ctl_path *path was being used in the
routine register_sysctl_paths() with a static:
static const struct ctl_path null_path[] = { {} };
Since this is a null path we can now just simplfy the old routine
and remove its use as its always empty.
This saves us a total of 230 bytes.

This script allows sysctl documentation to be checked against the
kernel source code, to identify missing or obsolete entries. Running
it against 5.5 shows for example that sysctl/kernel.rst has two
obsolete entries and is missing 52 entries.
