Fix spurious menu visibility: don't map child if parent is hidden 

In X11, child windows are only visible when the parent is mapped.
In Wayland, all frame_bufs are independent scene nodes. The menu
content window was being mapped at creation time (wMenuCreate),
making it visible even though the parent frame was offscreen/hidden.

Fix: wl_window_map skips enabling a child node if its parent's
scene node is not yet enabled.
