F11 to F12 update on s390x

[Andrew Avramenko]

Hello,

During upgrade from F11 to F12 on s390x I've got an error
rpmlib(PayloadIsXz) is needed. I know how to fix it on x86, just need
to update rpm from updates repo, but it seems there is no such repo
for Fedora on s390x. Could You please tell how to fix that? Thanks.
