I think I have found the root cause of the problem.

Mock runs the 'yum resolvedeps' as the calling (unprivileged) user. This
means that yum cannot download the filelists.sqlite it needs to resolve
the dep.

It was part of a general strategy of trying to run everything that had
user-input components in an unprivileged env.

I can remove the privilege drop around this call and that should fix it.
