[TT-1992] use CTF/lib that supports Docker running go-ethereum v1.15.0 (

#16477)

* use CTF/lib that supports Docker running go-ethereum v1.15.0

* use CTF versions that use go-ethereum v1.15.0

* make sure thet eth client used with Seth is ethclient not simulated.Backend

* try another commit

* use tagged CTF versions

* add changeset

* remove havoc.Schedule calls
