linux-utils: combine cpupower and turbostat into a split pkg

Merge separate Makefiles into a single split package following the
pattern used by Arch Linux and other distributions.

This reduces code duplication, simplifies maintenance, and makes it
easier to add more kernel tools in the future. Both packages remain
independently installable with no functional changes.

Closes PR#28272
