cyclictest - minor change request for histogram

[Nicholas Mc Guire <der.herr@hofr.at>]

HI !

 minor change request to the histogram in cyclictest to record the
 comandline - needed for confused people like me ...

 I would prefere if the commandline with the parameters used during the
 test-run would be recorded in the histogram output - thats what the 
 below patch does. i.e. runing:

hofrat@debian:~/rt-tests$ ./cyclictest -q -p 10 -n -h 50 -l 1000

would result in the histogram begin displayed as

# cmdline: ./cyclictest -q -p 10 -n -h 50 -l 1000
# Histogram
000000 000000
000001 000000
000002 000000
...

thx!
hofrat
