cmake: bump minimum required version to 3.17

also set cmake_policy version to 3.17...3.19 enabling all policies
present in CMake up until 3.19.
CMake 3.19 contains the newest policy we require (CMP0109) which makes
find_program() only check for executability but not readability which
allows to find sudo.
