[LIT][LLVMCPU] fix failing rvv lowering strategy test (#24739)

https://github.com/iree-org/iree/pull/24709 and
https://github.com/iree-org/iree/pull/24601 merged one after the other,
the CI did not run again in-between on the merge base of the latter.
This adjusts the tile sizes selected according to the former.
