xcb: Show buttons on the title bar for QWindow

Browse Source 
QWindow by default doesn't have the window flags to display
buttons on the title bar and it's up to the window manager
whether they will be shown. For example, fluxbox doesn't show
the maximize button.

The cocoa plugin and the windows plugin adjust the window
flags in this special case of QWindow to show some buttons,
so do the same in the xcb plugin.
