[test] Rework how default timeout is handled.

[test] Rework how default timeout is handled.

The slow_archs list had only an effect when no timeout was
passed. Now it will also increase the timeout on the bots.

Also simplified the code a bit.

PTAL. The old behavior has a not so obvious pitfall and CLs like this
https://codereview.chromium.org/1869683002/ have not the desired effect.

LGTM!
