wl_backend: fix frame button click dispatch (close/iconify) 

frame_buf_at was preferring parent frame_bufs over smaller children
(buttons), so clicks on the close/iconify button area were dispatched
to the titlebar instead. Fix by preferring the smallest frame_buf
that contains the pointer position.
