(broken, experiment) Lowering the load factor did improve the peek-skip rate

Changing initial hash to (rabin_val ^ (rabin_val >> 16)) is actually
quite a bit worse overall. Though it looks like it was 'unstable' and not giving
identical pack file output. >>24 seems to be better, but doesn't improve anything.
In both cases, it is clear the extra bits don't help peek skip rates, so it isn't
helpful.
