rpm-ostree: 2016.1 -> 2016.10

This also updates a bunch of its dependencies to enable the update,
and gets rid of libhif because upstream stopped maintaining it as
such, instead using it internally in other projects until they can
agree on an interface for it. Nothing seemed to be using libhif so
I'm not too concerned about removing it.
