Drop Eclipse from Scientific images

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

https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/KQV3XN7CYCRCP5ENU5PNNWGRB7Z3YQIZ/
https://bugzilla.redhat.com/show_bug.cgi?id=1964630
https://bugzilla.redhat.com/show_bug.cgi?id=1987435

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.
