gather-dnf: Run latest() later

The initial version of the filtered the latest builds at the start. That
doesn't matter in many cases:

* When there are no lookaside repos, there is generally a single version
  of each package.
* When lookaside repos do not overlap with compose repos, or contain
  only older versions.

It is however a problem when the lookaside repos contain higher version
of a package than what is in a compose repo, and some package explicitly
requires the older version.

Consider this scenario:

* lookaside contains bar-1.1
* compose repo contains bar-1.0 and foo-1.0
* foo-1.0 `Requires: bar < 1.1`

The original code would filter out the bar-1.0 package, and then fail on
unresolved dependencies.

This patch moves the computation of latest packages much later, to part
of code where all options to satisfy a dependency are selected and the
best match is chosen. At that point if there are multiple versions
available, we do want the latest one.
