kibana7: drop

Depends on EOL software and no maintenance has been attempted to change this after a ping
(https://github.com/NixOS/nixpkgs/issues/259178)
Feel free to adopt and re-introduce if you care about this software.

This will probably seriously hamper ELK usability in nixpkgs, but as it
receives no maintenance…
