Remove unrelated poster img and video links in custom_header_video.html in exampleSite

Hi there,

it looks like there are some obsolete file URLs in custom_header_video.html in exampleSite.
This is a bit irritating for new users to the Hugo scroll template (like me) imho. 😉

yes, this could be related to recent changes related to i18n, I'll try having a look at that sometime this month.
