powertop: update to v2.9

* Upstream filename added "v" before version:
  - Add UPSTREAM_CHECK_REGEX
  - Update SRC_URI to include the "v"
  - Point ${S} to proper directory

* Patch for required headers no longer needed in current upstream
* Tested on qemux86-64 core-image-full-cmdline image with multilib
