[koji PATCH 1/2] use the closest newer build not the latest

[Dan Horák]

Recently when a build is missing, the prefer_new option is set and a newer build exists,
the latest build is included in the buildroot. We should rather be using a closest newer
build if it exists, the latest one can be too new, with different dependencies etc.
