No longer name the packageSetChains after the package set, but
keep them named after the pipelines. This should be a
non-functional change as dnf-json does not care about what the
chains are called, only that the names are unique.
Add F34 and F35 image test cases for all remaining image types, which
were previously not tested. With this PR, image test cases are now
generated for all image types on all architectures as supported by the
Fedora distro definition.
