[gnome-boxes] installer-media: Add installed_size property

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

    installer-media: Add installed_size property
    
    It represents the storage allocation of the OS immediately after
    installation. We only know the value of this property for express
    installations. This information should really come from libosinfo and
    hopefully it soon will be, along with the rest of the OS-specific express
    installation code/data.
