Massimiliano Culpo b14f18acda microarchitectures: look in /sbin and /usr/sbin for sysctl (#13365)
This PR ensures that on Darwin we always append /sbin and /usr/sbin to PATH, if they are not already present, when looking for sysctl.

* Make sure we look into /sbin and /usr/sbin for sysctl
* Refactor sysctl for better readability
* Remove marker to make test pass
