build: drop relup for edge edition

* the edge edition is completely dropped in v5
* typically reboot is acceptable for edge brokers
* we do not know how many users are using it
* we never really seriously tested relup for edge edition
* now there is an issue in relup which will fail edge edition
  not worth the investment to fix
