Add qemu 4.2 and libvirt 6.0 patch (openstack wallaby) #33

I tested these 2 patches and no error occorred. You can check it :)

Hi!

Thanks for libvirt 6.0 patch! I merged your commit after editing it.

However, QEMU 4.2 patch was already there, so I removed it from the merged commit.

I assume the existing version should be fine for you?

Anyway, thanks.

I'm building QEMU 4.2 from Openstack Wallaby repo and I need to edit /debian/rules to convert images successfully. Without it, qemu-img convert process will be stuck at 3% all the time
