Drop Eclipse from Scientific images
    
    Eclipse has been orphaned and does not build or install in F35
    or Rawhide, see:

    The Scientific images currently fail to build because they try to
    pull in Eclipse packages which are not installable. Since it
    doesn't seem likely that Eclipse will get fixed, let's drop it.
