    Let the CI build with srcdir != builddir again
    
    This got lost in the recent CI overhaul and IMO it is a useful thing
    to do as it catches common problems in Makefiles that would otherwise
    only show up later when 'make distcheck' is run.
    
    Also upload more artifacts when tests are failing, and none if all
    the tests pass.
