  CostModel/RISCV: tweak test for ctpop, with/without ZVBB (#67013)

Vector ctpop only exists under ZVBB, but ZVBB is unaccounted for in the
cost-model of ctpop. Document this defect with an additional RUN line in
the test for ctpop, showing identical costs with/without ZVBB. A
follow-up patch could fix this defect.
