[Libguestfs] supermin in Fedora Rawhide switched to using dnf instead of yum

supermin needs to download packages (eg. RPMs) when preparing the appliance. 'dnf download' finally appears to have made parallel downloads reliable[1]. Better late than never. So I have experimentally switched Rawhide's supermin to use 'dnf download' instead of the (deprecated) 'yumdownloader' program. This only affects the 'supermin --prepare' phase, which means it only affects people building libguestfs from source. Ordinary use of libguestfs, even in Rawhide, should be unaffected. If you are building libguestfs from source on Fedora please try the new supermin + dnf, and let me know if you find any problems. Rich.
