[gnome-contacts] cc-crop-area: Highlight circle and only draw corners

[Niels De Graef <nielsdg src gnome org>]

commit c5a446b0235f02a4a6437919e4a6539f6c6327c6

    cc-crop-area: Highlight circle and only draw corners
    
    The preview was a rectangle previously.
    
    This commit darkens the background further, highlights
    only a circle and not the rectangle and draws only the
    corners and not the whole rectangle. These changes were
    made according to new design mockups.
