Update builder image to include new goveralls version, remove ppc64le

As fedora 30 builds seem to have disappeared from copr
we update base to 31. We update libvirt-devel to 5.6.0, remove the
virt-preview copr repo, and remove gradle also.

Wrt/ fvbommel/util#6 we need to apply a patch
to be able to resolve a dependency in order to build pr-creator and the
like.

Lastly we need to remove the ppc64le arch build as the required builds
for that arch are missing in the repos.
