Refine the binder latency test
* limit the output line length be be under 80.
* fix the target service when pair > 2

Support halt the trace when schd-dbg hit deadline
Usage:
start atrace as usual:
>atrace --async_start sched freq ...
then use schd-dbg with -trace arguments
./schd-dbg -trace -deadline_us 2500
This makes schd-dbg to stop trace once it detects a transaction
duration over the deadline. By writing '0' to
/sys/kernel/debug/tracing and halt the process. The tracelog is
then available on /sys/kernel/debug/trace

This test is used to check if the kernel scheduler
1. supports priority inheritance.
2. utilize the sync flag.
It also make statistic on average, best and worst latency
as well as number of deadline miss with a configurable
deadline specified in us.
The output is in json format hopefully to make it easy
to integrated with present test framework.
usage:
./schd-dbg # test and output json
./schd-dbg -i 1 # number of iterations
./schd-dbg -pair 4 # number of process pairs
./schd-dbg -deadline_us 2500 # deadline in us
./schd-dbg -v # debug
Test: pixel
