mod_http_oauth2: Tweak method of centering the UI
The percentage here was relative to the viewport width, which on some
very wide screens may put the UI slightly outside of the view, requiring
scrolling to see.
By using a unit relative to the height of the viewport, this is avoided
and should work better. But no guarantees, it's still possible to resize
the browser or adjust font sizes so that the UI goes out of view.
