x11: Always update shadow size

Not updating shadow size unconditionally would lead to shadow size not
being set on map, which would lead mutter to think that we are a Window
without extents and then become confused when we suddenly set some.

Make sure that doesn't happen by always having shadows set on map, just
like GTK3.

Fixes #4136
