This old openstack package brings in centos-release-ceph-nautilus
which actually has an incorrect mirrorlist entry in it's .repo file
that tries to point it at the centos-8 repos [1]. When upstream
retired CentOS 8 this stopped responding. Update to Xena (we don't
rely on any of these bits, it's just one or two packages we need
bindep to install for the wheel builds).
