fix: u128 panics bench.rs

Since benches are meant to measure performance not correctness, the following u128 benches have added wrapping in order to prevent panics. The other Uint128 tests did not panic, so they were left as is;
e.g.
Benchmarking u128/right shift: Warming up for 3.0000 sthread 'main' panicked at math/benches/bench.rs:50:54:
attempt to shift right with overflow
