Avoid infinite loop in old versions of IO::Uncompress:Unzip

TravisCI found a bug in its perl:5.12 image where we stumbled across an
infinite loop bug in IO::Uncompress::Unzip:

    https://bugzilla.redhat.com/show_bug.cgi?id=806373

It's fixed as of IO::Uncompress::Unzip@2.030, so we specify that as our
minimum version, such that upon install we can be reasonably sure we
have a patched version of the module.
