color: Remove profile upload feature

As it was already removed in colord itself: https://github.com/hughsie/colord/commit/98f83acc910f527496fc149511c9dfa35f954be9#diff-cb19db05cc548372b27ebee7d47bc00b6788ad05da6f5d7fff107c45bbfba38f

This removes the only direct libsoup 2.x dependency in gnome-control-center.
