[gnome-shell] StIcon: Remove content-image capability

[Owen Taylor <otaylor src gnome org>]

commit a9a8b1ec6aa19ca92816140edd9f020620e10eb4

    StIcon: Remove content-image capability
    
    The ability to set a "content image" on an icon relies on the ability
    to have custom theme properties of a "border image" (9-slice) type.
    We don't have this, and the capability of a bordered image specified
    by the theme can be achieved more naturally with standard CSS facilities.
