[gtk/matthiasc/for-master] linkbutton: Use the LINK role

[Matthias Clasen <matthiasc src gnome org>]

    linkbutton: Use the LINK role
    
    It is a bit ambiguous, but I think link buttons are
    more links than buttons. See WAI-ARIA for a discussion
    of the differences.
    
    Update tests to match.
