Subject: [PATCH 2/2] selftests/intel_pstate: cpupower command not found

Running "make kselftest TARGETS=intel_pstate" results in the
following errors:
- ./run.sh: line 89: cpupower: command not found
- ./run.sh: line 91: cpupower: command not found
if the cpupower is not installed.

Since the test depends on cpupower, this patch stops the test if the
cpupower is not installed.
