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

[Richard W.M. Jones]

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.
