Subject: [PATCH] cyclictest:Appended man & usage about the same priority of many threads with -h
If we run a many threads with -t option, "priority--" rt priority will assign
per thread in sequence. But, If we use -h option, all threads is same priority.
Append man page and cyclictest usage about the same priority of many threads
with -h option.
ex) cyclictest -t 5 -p 50 [enter] <-- without -h
ex) cyclictest -t 5 -p 50 -h 100 [enter] <-- with -h
