Subject: [PATCH] DNF 3: workaround a bug with config values that are lists

There's a bug / overly-clever-design flaw in DNF 3 that prevents
us appending to config values that appear to be lists, even
though lists should be mutable objects and this *ought* to work
(and did work in DNF 2):

https://bugzilla.redhat.com/show_bug.cgi?id=1595917

This works around it.
