[gtk/text-drag-select] textview: Only claim the event when appropriate

[Matthias Clasen <matthiasc src gnome org>]

commit c959f9c7012b1d244a972519397862d8ff99bc58

    textview: Only claim the event when appropriate
    
    Don't claim the event unconditionally for the click gesture,
    since we may want to start a drag selection.
    
    Fixes: #2999
