[crux-contrib] dropped ports

I've dropped sepens ports from contrib in 3.4. If you see one that you would like to maintain or a port that one of your ports depend on, speak up. The list is available here: https://crux.nu/gitweb/?p=ports/contrib.git;a=commit;h=6a2fc0c3a2654189815dd... Thanks, -- Fredrik Rinnestam
