blktests: make block/026 run in constant time

The original test just did 4g of IO and figured out how long it took to
determine if io.latency was working properly.  However this can run
really long on slow disks, so instead run for a constant time and check
the bandwidth of the two cgroups to determine if io.latency is doing the
right thing.
