Use version of erlang < 1.25 and fix EL8 passlib

Use the CloudSmith rabbitmq-erlang packages rather than the LaunchPad erlang packages for Debian installations, so that we can specify a 24.x version of the rabbitmq-erlang. (25.x and 22.x are only available in LaunchPad for Debian and fail with latest rabbitMQ).

We no-longer want to use the latest 1.25 that is available in the rabbitmq-erlang repository, as this means that rabbitmq fails to install, and instead reports error:

Resolves #312

Seems to be a problem with dependencies. I have been unable to install erlang and rabbitMQ compatible verisons on U20 using the repositories we currently use (LaunchPad ones). Also affects U18.

1) Previously we installed version 1:24.3.4-1rmq1ppa1~ubuntu20.04.1 when it was working successfully - for erlang-base etc. But this version doesn't seem to be available any more on the LaunchPad apt repository. 2) The latest erlang-base etc version I can find is 1:22.... 3) If you use the older erlang-base then you can't install the latest rabbitMQ as it requires erlang >= 1:23.2

So either: 1) we need to find the erlang-base, erlang-asn1 etc 1:24 versions we used before. But I've not managed to find it in the repos we set:

$ apt list erlang-base -a
Listing... Done
erlang-base/focal 1:25.0-1rmq1ppa1~ubuntu20.04.1 amd64 [upgradable from: 1:22.2.7+dfsg-1]
erlang-base/focal,now 1:22.2.7+dfsg-1 amd64 [installed,upgradable to: 1:25.0-1rmq1ppa1~ubuntu20.04.1]

2) Have managed to get compatible set of erlang repos from "erlang solutions" repos, see https://www.rabbitmq.com/which-erlang.html#erlang-repositories If we use this repo and install version 1:24.3.3-1, then I was able to install rabbitmq-server

Also the older erlang repositories seem to be available at their cloudsmith repos: https://cloudsmith.io/~rabbitmq/repos/rabbitmq-erlang/packages/?q=erlang-base

3) I've found the erlang group package 1:24.3.4-1rmq1ppa1~ubuntu22.04.1 is available at https://launchpad.net/~rabbitmq/+archive/ubuntu/rabbitmq-erlang/+packages?field.name_filter=&field.status_filter=published&field.series_filter= But if I attempt to install that it complains about missing dependencies - so that doesn't seem to work

4) If we go back to the earlier erlang-base etc that is in the LaunchPad repository then we would have to rollback rabbitMQ version as well - and ideally we don't really want to rollback erlang and rabbitmq versions...
