Upgrade rand_emmc_perf to check for worst case behavior
Add the -s <count> option to do that many random 4K IOPS, and
then report the average and max times/operation, and the standard
deviation of the data set.
Add the -f <file> option to save the complete set of times for
each I/O of a -s run. This can be used for further analysis.
Also, update the android_emmc_perf_tests.sh script to know about
the new -s and -f options, and add support for the Flo device.
