programs/will-it-scale: use native python3

This reverts ddd4c73 ("tests/will-it-scale: use python3.8 to run will-it-scale")

This simplies the build of will-it-scale and resolves issue reported
on fedora 38 [0].

The downside is it causes that will-it-scale can't run on distro which doesn't have
native package for pyhon3.8 and above.
