[gnome-control-center/wip/rishi/background-remove-grilo] background: Drop the unused build dependency on Grilo

[Debarshi Ray <debarshir src gnome org>]

commit d0612cca1fc4ada1a45d9477bdbad6fba15eb57c
Author: Debarshi Ray <debarshir gnome org>

    background: Drop the unused build dependency on Grilo
    
    The code that uses Grilo to fetch the user's Flickr photos isn't
    actually used by the Background panel, to the extent that the final
    binary doesn't even link against Grilo. Getting rid of this unused code
    will ensure that distributors aren't needlessly pulling in this
    dependency.
