Newer kernels have HRTICK_DL which is a HRTICK for the deadline
scheduler only.

In addion newer kernels rename
/sys/kernel/debug/sched_features
to
/sys/kernel/debug/sched/features

These changes use HRTICK_DL if available and make use of the
new file name in a backwards compatible manner.

These changes are based on changes in util.c in the stalld program.
The stalld program itself was based on code in the sched_deadline
programs in this suite.

John Kacur (2):
  sched_deadline: Accommodate new location of HRTICK file in kernel
  sched_deadline: Use HRTICK_DL for sched_deadline tests
