Now the artwork requirements have been split out of these tests,
we can reasonably report results for them from install_default
and install_no_user jobs.
As checkwiki reports, reporting from Everything and Atomic jobs
will fail, but this isn't really a problem. We should probably
have a 'Minimal' column for x86_64 (but then we'd have to invent
a '$SUBVARIANT_OR_MINIMAL$' or '$PACKAGE_SET$' substitution, or
something, to get from 'Everything' to 'Minimal'), and we could
have an Atomic column, but I don't think we really need to block
on either of those things. For now this will get us all the most
important results.
