Fix unclickable URLs with scrolled viewport

Since scrolling the terminal moves around the underlying data structure
of the terminal, the URL selection would search for the URL at the
position where the click would have been without any scrolling.

By adding the viewport offset to the click position, the URL clicking
now searches at the correct location.

This fixes https://github.com/jwilm/alacritty/issues/2076.
