hgweb: rely on a specific class to change cursor type in followlines UI

The previous CSS rule would also apply in pages where followlines UI was not
available (e.g. "changeset" view at /rev/<node>/). We insert a
"followlines-select" class in JavaScript on actually selectable lines and
restrict the CSS selector to use it.
