[deps] revert "Update V8 DEPS." with a depot_tools bug

This reverts commit 8f68e392.

Reason for revert: depot_tools started using Python3 by default with this deps roll, but it contained a Python3 bug. Reverting this and waiting for a new deps roll will fix the issue since the latest depot_tools contains the fix for this issue.
