Fix off-by-one error with binderThroughputTest -s
The -s option to binderThroughputTest allows the user
to set the size of the payload being sent during the
test. Due to an off-by-one error, the size was actually
4 bytes less than specified. Fixed.
Test: verified correct size

Fix binderThroughputTest -m option
The -m option allows the user to specify the estimated
max latency to calibrate buckets used for percentile
calculations. The option didn't work because the
time_per_bucket was not being set so the default value
was used.
Test: verified correct -m operation

Fix percentile calculations
Adjust max latency in running binderThroughputTest
to improve percentile accuracy. We used to use a fixed
max latency which is devided into time buckets to obtain
the round trip latency percentile. The actual latency,
however, can be much smaller than the max latency, which
results in measurements from all iterations ending up in
the same bucket and leads to inaccurate percentile
measurement. This is resolved by either performing a
training round (option -t), which sets the max latency to
two times the worst latency during training, or by providing
a max latency (option -m) in millisecond by the caller.
Use --help option to see usage.

Fixes: 62660944
Test: Running "binderThroughputTest -p -w 2 -i 10000 -s 0" on marlin-3.18 used to show the same percentile values for 50%, 90%, 95%, and 99%. Now with -t flag,percentile values are different.
