Replace ninja with ninja-samurai

Make is kind with -l$(nproc) but not ninja unless we create a wrapper for the command to inject -l$(nproc). But maybe we have a better option: ninja-samurai which claims to be able to replace ninja.

We had #635 before, and now ninja builds significantly delays make, cause kicad-git to timeout. (There was another suspectious case some days ago.) Please try this solution and if it works, let's use it.

No, it doesn't have -l. A hack is needed :-(
