Obsolete qemu-virtiofsd

The qemu-virtiofsd package was deleted in 8.0.0, so to get dnf to
install virtiofsd during upgrade we need an Obsoletes line. If
something had a "Requires: qemu-virtiofsd" line instead of the
more recommended "Requires: vhostuser-backend(fs)", the fake
Provides will satisfy it.
