Previously, arrays defined by struct ctl_path is terminated

The optimization has been implemented in the previous patch,
here to remove unnecessary terminate ctl_path with an empty one.

If these things are built-in, can you verify you're saving bytes
with size before and after the patch?

I wonder if having something like DECLARE_SYSCTL_PATH_ONE() would make
this nicer on the eyes, and also useful for the other changes you
are making. Do you have many other single path entries you are changing
later?
