Rename $scenario/overview into $scenario-overview

That we have breadcrumbs instead of 'Back' buttons, the previous layout
($scenario/overview) created a parent link to the steps for this
scenario:

	install » linux » usb » Install from Linux: overview

This commit makes them:

	install » linux » Install from Linux: overview

This will be especially useful for the upcoming download pages...
