[LayoutNG] Update stale baselines for two layout tests

For the following two layout tests:
- fast/events/background-tab-on-submit-ctrl-click.html
- fast/events/background-tab-on-submit-synthesized-ctrl-click.html

Their baselines were updated by crrev.com/c/1119380, which left their
NG-specific baselines stale, and made them fail on layout_ng bot.

This patch updates the baselines to make them pass again.
