Add 16h cyclictest shuttle measure

Uses cyclictest from the rt-tests test suite to measure wake-up latency. A real-time thread is run on CPU1, and wakes up at a regular interval (specified by the interval parameter) using clock_nanosleep. It then uses clock_gettime and computes the difference between the scheduled wake-up time and the effective wake-up time measured by clock_gettime.
The command used is: cyclictest -p `prio` -a1 -t1 -n -h 200 -q -i `interval`
**Common test metadata:** Task priority: 98, Interval: 1000us, Boot Parameters: isolcpus,rcu_nocbs,irqaffinity, ETF qdisc delta: None, Device and processor load: None, qdisc: pfifo_fast
