Revert "wrapper: Temporarily disable -Wmax-tokens"

This reverts commit 3b2358092e00ab7904a873b516ac6aac832c2277.
According to crrev.com/c/2171058, the fix in chromium could work.
Will wait till the patch submitted in chromium and CrOS uprevs to
merge the change into CrOS.

Reason for revert: The workaround is not needed anymore.

Original change's description:

> fixed properly on upstream Chrome.
