benches: Added disk usage measurements to bench_wt

Browse Source 
Note bench_wt_seq's disk usage is garbage because of the repeated
truncates!

But I figured this is at least useful for the other benches, and we
already have bench_helper_usage. Maybe in the future we'll figure out
some way to get useful disk usage from bench_wt_seq.
