sysctl: remove register_sysctl_paths()



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.
