Reland "Roll per-builder build-dir experiment to all (try.)chromium.fuzz bots"

This is a reland of commit bd6a952830

Reason for reland: crrev.com/c/5967394 landed which should preserve
the old paths even when the build dir switches.

Original change's description:
> Roll per-builder build-dir experiment to all (try.)chromium.fuzz bots
>
> The experiment's been on the entire CQ for a while now. This starts
> rolling it to more bots.
