deps: revert backport b593aa8 from v8 upstream

This reverts commit 45f13304.

45f13304 was basically breaking
node-inspector. V8 landed a patch upstream that would probably fix these
issues (see https://codereview.chromium.org/813873007

), but without the
ability to properly test it in the wild, it's safer to just revert the
breaking change.

Fixes #8948.
