Subject: [PATCH] wayland: Always call Wayland_SetWindowBordered when showing
 the window

Otherwise our windows have no window decoration on compositors that
support xdg-decoration-unstable-v1, but default to client-side mode.

Contrary to what the comment was stating, there is nothing in the protocol
that would make redundant calls to zxdg_toplevel_decoration_v1::set_mode
problematic.
