Selftests fixes for futex and intel_pstate

This is followup to my previous patch [1] which was a very simple makefile change. After a comment from Darren Hart I updated intel_pstate as well, but noticed a few issues with running intel_pstate. That caused the change to expand a bit.

- fix build deps for futex test *original*
- update makefile for intel_pstate to be in sync with Bamvor's changes
- update cpupower frequency-info to fix intel_pstate test

For the linux-pm list the change to cpupower might be an issue, but if so it would be nice if they can suggest a better way to get the self test to do what it wants to do.

The series is based on Shuah's kselftest next branch, because that is where Bamvor's latest changes are:
