framebuffer: in onscreen_x11_get_xid return foreign xids

Browse Source 
If a foreign xid has been set on a CoglOnscreen then
cogl_onscreen_x11_get_window_xid doesn't need to defer to the winsys to
get the underlying window xid. This also means it's possible to read
back the xid before the framebuffer is allocated which fixes a crash in
the x11-foreign example app.
