[gtk/entry-sizing: 1/3] password entry: Fix sizing

[Matthias Clasen <matthiasc src gnome org>]

    password entry: Fix sizing
    
    Use the same sizing approach we use for GtkEntry:
    ignore icons when measuring. This ensures that
    password entries don't change size as icons come
    and go.
