Gabriel Charette 125f7cc4d5 [depot_tools] Cap num_cores to RAM/2GB under local jumbo builds
Also make autoninja.py a vpython script to use reliable version of
psutil.

Note: this change also makes autoninja always make a decision about
-j; there's no longer a default where it lets ninja pick. The code is
simpler this way and I think it's better because it lets developers
always see which -j is in effect when using autoninja (and that's its
exact purpose, if you wanted default you shouldn't have used autoninja).
