Updates for running IPLD-ETH CI tests (#414)

* random nits

* geth - visibility of migration status

* forward CERC_RUN_STATEDIFF to geth container

* fix ipld-eth-server vars

* fix fixturenet-eth-loaded stack

* fixturenet geth genesis - include mergeNetsplitBlock

* forward CERC_STATEDIFF_DB_GOOSE_MIN_VER to env file

* add TAG_SUFFIX arg to lighthouse build

  intended to avoid sporadic failures when running lcli on github CI runners, likely related to non-portable builds
