test(family): assert ioperm/iopl/modify_ldt classify as Misc
Audit of ioperm(2) confirmed the syscall is traced correctly: classified
as KindNull (name-only enter, no arg decoding) with the exit handler
capturing the raw int return value, matching the man-page semantics
(int ioperm(unsigned long from, unsigned long num, int turn_on) -> 0/-1).
ioperm and its x86 port/CPU-state siblings (iopl, modify_ldt) are not in
the explicit family table and intentionally fall through to Misc. Add
explicit family-classification assertions so a future regression that
accidentally remaps them is caught. No implementation change was needed.
