window: fix initial shadow width for maximized/fullscreen windows

To calculate the shadow width, we look at the value of priv->fullscreen
and priv->maximized.
Those fields will have the actual value only after GTK receives back a
window state event though, so they will be wrong in _realize(). Look at
priv->fullscreen_initially and priv->maximize_initially too, to avoid
the size changing right after realize, which would make the window
flicker if maximized at startup.

Good catch! But I'm a little worried that always looking at those initially bits might be risky, and maybe we should consider them only if !mapped.
Looking e.g. at gtk_window_maximize, we do set maximize_initially, regardless of whether we're already mapped or not.
