[gtk/issue-67] Disable GdkSurface.minimize on Wayland

[Emmanuele Bassi <ebassi src gnome org>]

commit 1ec4cb7f17111420bc125049031c267ef7291945

    Disable GdkSurface.minimize on Wayland
    
    The existing xdg-shell protocols do not support minimization in a way
    that allows us to implement the GdkSurface API; the only minimization
    operation does not come with a state notification, nor it comes with
    a way to undo itself.
    
    Closes: #67
