sysutils/lsof build failure under recent -current

Hi,

Since 9.99.18 I am not able to build lsof; I get:
...

....

ptrace.h includes module_hook.h only if _KERNEL is defined.

I am aware some don't like this utility, security and all; I myself
rarely use it, so am not bothered at all; perhaps it is an easy fix,
as the configuration process does not recognize 9.99.xx versions (it
assumes netbsd 7). BTW I can force the installation of lsof from
9.99.18 onto 9.99.24, it then apparently works, but the output is
partial garbage, which is understandable, I guess.
