cyclictest.py: make -n option default to use clock_nanosleep(2)

Bugzilla: 1382155

current default for cyclictest is to use itimers as the default timer
which was fine back in the day but now we should default to using
modern timer with hrtimer underpinings.

Add the -n cyclictest option to the default commandline to force
use of clock_nanosleep(2)
