cpupowerutils: use kernel version-derived version string
As cpupowerutils is intended to be included into the kernel sources, use the kernel versioning instead of a custom version. The script utils/version-gen.sh is largely based on the script already found in tools/perf/util/PERF-VERSION-GEN . Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
