test(generate): lock in mincore BPF handler wiring (zv)
Audit of mincore(2) confirmed the existing tracing is correct: KindMem +
FamilyMemory, with addr=args[0], length=args[1], and both flags and length2
held at zero. args[2] is the userspace 'vec' output pointer, not a flags
value, so it is correctly NOT wired into ev->flags.
Add TestGenerateMemHandlerMincore to lock in this wiring and explicitly guard
against the historical mistake of mapping args[2] onto ev->flags the way
flags-bearing siblings (madvise/mlock2/mseal) do.
